Tips for Surviving Alpine Switchbacks on a Motorcycle

This article was originally published in Motorcyclist Magazine.

Their names are infamous; Pordoi, Sella, Gavia, Gardena, and of course Stelvio. These are just a few of the mountain passes that snake up and over the mighty Italian Alps and jagged Dolomites. Riding these epic roads is not for the faint of heart or the weak of skill. Riding the steep hairpin switchbacks isn’t fundamentally different than riding any other twisty motorway, except these roads are turned all the way up to 11. But with a little knowledge and pre-trip cornering practice you can tackle the wicked Alpine passes with enthusiasm, rather than dread.

Sharpen your cornering skills – You’ll need to be really good at looking well ahead, judging entry speed, selecting effective cornering lines and leaning the heck out of your rental bike. You also need to understand techniques for managing both uphill and downhill hairpin turns. Article Link

Maintain uphill momentum – On the way up the mountain gravity works in your favor to help slow for turns. But, slow down too much and the bike will want to fall over. Minimize instability by getting on the gas early, but not so early so you run wide.

Control speed going downhill – When riding downhill gravity works against your attempts to scrub speed. This means you need to brake with greater force. To be safe, brake earlier so you can brake with less intensity.

Trailbrake – Get the bike slowed and help it to turn by braking past the turn-in point and then taper (trail) off the brakes as you lean more. Hold light brake pressure until the bike is pointed around the turn before fully releasing. Article Link

Use the rear brake – Apply the rear brake just before the front to minimize forward pitch and keep the wheels in alignment. Maintain light pressure on the rear binder for a moment after releasing the front brake to help “hook” the bike around turns.

Use Effective Cornering Lines – Enter from the outside or middle of your lane and don’t turn in too soon. Aim for a “delayed apex” that is about 3/4 around the curve so you’re pointed safely down the road and not at the oncoming lane or outside edge of the road. Cornering Lines Article

Drive out of each corner –Gradually accelerate as soon as the bike approaches mid corner to maintain speed and stabilize the chassis. Well-timed acceleration ensures a predictable path of travel.

Look where you want to go! Ken Condon photo

Use smooth brake-to-throttle transitions – Smoothly release the brake while simultaneously rolling on the throttle to avoid abruptness that can squander traction and cause your bike to exit wide.

Practice slow speed turning – You will need excellent slow speed control to prevent mid-corner tip-overs on the countless tight “slower than first gear” switchbacks. Maintain stability using steady clutch and throttle control. The tightest turns may require some rear brake and counterweighting. Article Link

Look where you want to go – The eyes are a powerful tool for helping direct your motorcycle. But, too often when we are anxious we look down and toward what we fear, which increases the likelihood of a mishap. Look at the solution, not the problem! Article Link

Dealing with tour buses and bicyclists is part of riding the Alps. photo Caroline White

Watch for buses and bicycles – If you ride the Alps someday, you’ll be sharing the ridiculously narrow Alpine passes with tour buses and bicycle riders. Look well ahead and plan accordingly to avoid a collision. Expect to stop and wait until it’s safe to proceed.

 

Do yourself a favor and bone up on your cornering skills before you hit the Alpine switchbacks. You’ll have a more enjoyable and safer experience.

10 Truths That All Motorcycle Riders Need to Know

Become a patron to support the website. Thanks

Here is a list of the top 10 things riders need to know (but often don’t):

1. Traction management and direction control are directly affected by load transferring to the tires.

2. Timing of deceleration, braking, countersteering and acceleration directly affects traction, direction control (line) and where the bike is pointed at the turn exit.

3. Intensity of brake and throttle application and handlebar inputs directly affects traction, chassis stability and direction control.

4. Specific Visual targets help to accurately read the road and minimize overspeed corner entry.

5. Dynamic Lane positioning is a critical tool for maximizing angle of view and conspicuity.

6. Trailbraking done correctly, maximizes stability, manages traction and refines corner entry speed and direction control at mid-corner and exit.

7. Even the best riders get into trouble if they don’t respect environmental limitations.

8. Electronic rider aids help manage traction; they do not create more traction.

9. Proper riding gear minimizes the risk of injury, but does not make you “safer”.

10. Reading lists like this can make you smarter about riding, but only application of knowledge can make you a better rider.

Video: Cornering Seminar with Ken Condon

Become a patron to support the website. Thanks

At the request of the district manager for the Northeast Region, I booked several dates during mid-to-late winter of 2018. One event was held at Wilkins Harley-Davidson, located in South Barre, Vermont. As with each of the talk, around 100 people attended to learn about cornering…or learn more about cornering. Wilkins recorded the seminar in its entirety.

My aim with these talks is to spread the good word about the benefits of life-long learning…safety and MORE FUN and satisfaction. A secondary goal is to encourage participants to join me for one or more of the training opportunities I offer or am involved with.

And finally, I bring a stack of books for people to buy.

OK. On with the show. It’s over an hour long, so find a comfy chair.

Guest Writer: Why Street Riders Benefit by Riding the Track

Guest contributor Ed Conde shares his experiences about how track days have helped his street riding.

The Next Level

I came to riding late. I did not begin riding until I was pushing 50. I tried to make up for lost time by training and reading everything that I could find. I took the Motorcycle Safety Foundation Basic Course and the MSF Experienced Riding Course multiple times. The books and the courses definitely helped my street awareness and slow speed skills. However, I felt that these tools did not adequately prepare me for riding at speed on the street.

I tried improving my street riding by working on a skill or two each time I rode. I regularly practiced threshold braking, swerving, and weaving in parking lots. All of this helped a lot, but I felt that something was missing. I found that something when I began to do track days.

Some Benefits of Track Days

The three crucial things that track days provided were:

  1. Observation and feedback from track professionals.
  2. Action photographs that captured my riding and body position.
  3. The ability to repeat the same corners at speed without cars or other distractions.

Observation and Feedback from track professionals – There simply is no substitute for having an expert follow and observe you riding at speed. The difference between my perception of my riding and what experts saw was pretty sobering. I suspect that most of us are not as good as we think we are. Track instructors and control riders noticed that that my body position needed improvement, that I needed to relax, that my lines needed improvement, that my shifting needed work, and that my throttle/brake transitions needed to be smoother. This was a bit shocking considering how much time I had devoted to riding technique.

Action photographs – Photos do not lie! I have hated some of my track photographs because they captured all of the things that I was doing wrong. Track photographers often take photos at different curves and from different vantage points. My track photos gave me great feedback on my riding, although I did not always like what I saw.

The ability to repeat corners at speed – Being able to repeat the same corners at speed allowed me to see how changes affected my riding. It is impossible for me to duplicate this on the street where corners vary and hazards abound. While I practiced skills like trail braking, countersteering, downshifting, cornering lines, and body position in parking lots, everything changed at street speeds. Braking and downshifting from 30mph in a parking lot was a lot different than braking and downshifting from 65mph into a hairpin at the track. In addition, following an actual road was more realistic, for me, than following a cone course in a parking lot.

Are track skills useful on the street?

Folks often ask if the skills I learned at track days are transferable to the street. My answer is absolutely! Where else can you work on your riding skills safely at actual road speeds? While many skills learned at a Basic MSF Course or a “Ride Like a Pro” Course are extremely valuable, slow speed skills are often opposite to those I need at speed. While favoring the rear brake and counter weighting may improve my slow speed riding, it hinders my riding at speed.

Body Position Practice

Perhaps the best example of personal improvement from track riding is in my body position. (click on photos for larger image)

Track2009labeled
Figure 1

Figure 1 is a video screen shot of my first track day with Tony’s Track Days at New Hampshire Motor Speedway in 2009. At the time, I felt like I was riding well and actually passed most riders on the track. Looking at the photo now, I can see that I am almost scraping hard parts even though I am not riding fast. My upper body is leaning away from the turn and my eyes are not looking through the turn. I am pushing the bike beneath me dirt bike style which made me feel like I was really leaning.

HudsonLabeled
Figure 2

Figure 2 is a photo from 2011 taken near Bear Mountain, NY. I am trying to work on lessons learned at the track. I am no longer pushing the bike beneath me and my head is turned somewhat. The centerline of my jacket is now in line with the center of the bike. Despite some improvement, the footpeg is almost scraping at a modest lean angle.

DragonLabeled
Figure 3

Figure 3 is a photo from 2013 at the Tail of the Dragon. I had actually been working hard on skills learned at the track before this trip. The centerline of my jacket was now inside the centerline of the bike. My head turn was much better and I was beginning to weight the inside half of the seat. This photo is a big improvement, but I was still almost scraping my left footpeg at a modest lean angle.

TrackCurrentLabeled
Figure 4

Figure 4 is after multiple track days in 2014 and 2015. My head and shoulders are now lower and well inside the centerline of the bike. The head turn is better and almost all of my weight is on the inside half of the seat. I am not scraping despite a more pronounced lean angle. While I will not usually hang off this much on the street, I will use the better head & shoulder position and the weighting of the inside half of the seat on all my street rides.

 

Safer and More Confident Cornering

I will definitely use the skills that I have been learning at the track to ride better while conserving lean angle on the street. By keeping lean angle in reserve, I will have a safety margin if I need to tighten up my line during a curve. I will continue to attend parking lot courses because many fundamentals are learned best there. I will continue to practice slow speed skills with counter weighting, head turn, and dragging the rear brake. I will continue honing my street awareness skills and ability to anticipate trouble. However, I will not neglect training at speed with the help of professionals. I still have a lot to learn, but look forward to the challenge.

Editor Ken: Even if you ride a cruiser, tourer, ADV bike, or whatever, there is a track day for you. Non-Sportbike Track Days are available, as well as “traditional”sportbike track days . Either type of track day allows street riders to advance their skills in a safer environment than the street.

Crashing Sucks: Ask Me How I Know

Collarbone-XRay
Broken Clavicle

I crashed. In the scheme of things, the mishap wasn’t a huge affair. I was only traveling about 15 mph when I tucked the front tire of a brand new Ducati Multistrada, but the vertical force was enough to pop my collarbone. It can clearly be seen on the medical imaging, which may be utilizing services such as TestDynamics.

Dirt bike riding and road racing aside, it’s been quite a while since I last found myself on the ground next to or underneath a motorcycle. In such situations, it’s crucial to get yourself checked at urgent care services in downers grove.

My last road mishap was in 1978 when I fell victim to a dreaded left-hand turner at an intersection. I took a ride in the blinky bus (aka ambulance) but was promptly treated and released. My 1973 Yamaha TX650 didn’t fare as well and was sold for parts. Riders who also got injured in a vehicular crash may seek legal assistance and personal injury legal advice from a motorcycle accidents personal injury attorney when filing a claim.

This most recent crash involved a street bike, but didn’t happen on the street, rather it occurred during a joint Bosch/Ducati press event in Detroit Michigan on the gravel test track at the Bosch proving grounds. You see, I was invited to test the most-awesome safety electronics found on the newest Ducati Multistrada. FYI, the cornering ABS is truly amazing.

Racing Crashes Don’t Count, Do They?

Racetrack crashes have also been relatively rare but do occur a bit more frequently, which is the result of pushing the limits or vying for a podium finish.

My previous track crash happened about 3 years ago when I pushed the front tire of the Twisted Throttle BMW S1000RR a bit too hard (I sense a theme) into a cold and slightly damp turn 11 at Loudon trying to get a good knee down photo. No injury, but a truckload of embarrassment.

A few years earlier I fell in turn 5 at New Jersey’s Thunderbolt Raceway when an old and cold front tire finally gave up and lowsided me onto the pavement. No injury to me, but the bike flipped and stuff broke. Despite the bike looking bad, both the ZX6R and I were back on track within two hours time.

A few racing crashes between those two mishaps round out my thankfully brief crashing resume. That’s really not too bad considering I have ridden a lot of street and track miles over almost 40 years with many of those miles dragging knee on the racetrack.

Crashing the “Uncrashable” Bike

Like I said, the crash that involved the new Ducati Multistrada, and resultant fractured clavicle, wasn’t a particularly big one.

I simply countersteered the bike a bit too hard while entering a turn on the gravel test track and lost grip at the front tire. I fared worse than the bike with the Multi suffering some cosmetic rash and a broken hand guard.

Before anyone blames the technology, this crash was not the bike’s fault! The Bosch electronics are designed to prevent braking and accelerating miscues, not manage the effects of pushing a front tire too hard into a turn. And since I was not on the brakes when I tucked the front tire, the bike is not to blame. These systems only manage available traction (when braking and accelerating); they do not create more traction! Read More about the Truths About Electronic Stability Control.

Why?

You may be asking why I would do such a silly thing. Surely I know enough not to push a 500+ pound street bike with quasi-dual sport tires on gravel, right? Yes, normally I would have never pushed the bike this hard, but what caused me to do this admittedly dumb thing stems from four factors:

  1. I was fooled into a false confidence: I had just performed mind-blowing feats of daring on wet pavement that warped my basic understanding of physics. This was possible because of the absolutely awesome Bosch electronics package that is integrated into the Multi. Traction control that allows hamfisted throttle inputs while dragging footpegs in the rain! Maximum braking on wet pavement while leaned at 37 degrees! Unbelievable.
  2. I was tired: Testing the TC and Corner ABS for like 20 minutes made me a bit woozy and I had barely recovered when I took to the gravel track. “Just one more run” was one run too many.
  3. A photographer was pointing his evil lens at me: This isn’t the first time I’ve pushed harder knowing that a camera is pointed my way. Most times, I simply drop a little deeper into a corner and turn my head a little farther to ensure my body position and general awesomeness is captured. This time, I was trying for the best action shot that would accompany the magazine article.
  4. I have just enough off-road confidence to get myself in trouble: I had already done 5 runs on the gravel course and was impressed with the way the Pirelli Trail II tires worked as I drifted the bike out of the corners using the limited traction control setting in “enduro” mode. But, when push came to shove, I wasn’t in quite the right position and was too slow on the throttle to keep the front tire from plowing through the gravel.
  5. I didn’t heed warnings coming from my inner voice: In hindsight, my inner voice told me to call it a day. I had acknowledged to myself that I was tired. But, just before I fell I made a few mistakes that indicated that I was pushing beyond my ability at that particular moment. My voice of warning was speaking, but did I listen? No.

Being “that guy”

As I got to my feet and shut off the engine I was in utter disbelief. Had I really just dropped a brand new Ducati? With shock wearing off, my inner voice began tormenting me with doubts about my professionalism, competence and judgment. Not surprisingly, the Ducati and Bosch folks were gracious about the whole thing (apparently this happens more than people think).

I ride motorcycles, and I ride them hard. So, I should expect an occasional mishap. However, part of me actually thought I had somehow trained myself out of being human, insulating myself from simple mistakes. While I have worked hard to be the best rider I can be, I am not (yet) perfect.

Getting Over It

My collarbone is healed after 8 weeks and I’m back on the racetrack and street. As expected, part of me is a bit spooked about gravel surfaces, but not enough to matter. I’m back to riding hard and feeling good again. A big reason why I bounced back quickly is because I know why the crash happened and how to avoid it in the future. It’s a lot tougher when you don’t know what happened and don’t know how to avoid a future crash…that can get into your head and under your skin.

To avoid a similar crash in the future I’ll be more mindful about my limits at any given moment.

Truths About Electronic Stability Control

Bosch-CornerABS-rain
Grab the brakes or whack the throttle while leaned, Bosch has your back. Rain or shine.

The newest Ducati Multistrada has super sophisticated Bosch Traction Control and ABS electronics. These rider aids will make it a whole lot harder to crash! But, are they all they are cracked up to be?

The Bosch electronics I tested at the Bosch proving ground near Detroit included updated ABS with Combined Braking Systems (eCBS), Ducati Wheelie Control (DWC), Lift (Stoppie) Control, Ducati Traction Control (DTC) and Cornering ABS, aka Motorcycle Stability Control (MSC).

The straight-line ABS is nothing particularly new, but the introduction of corner sensitive traction control and Corner ABS certainly is. The brain behind this technology is the Inertia Measuring Unit (IMU) that can detect angles of roll, yaw, and pitch. With this data, the ABS and Traction Control systems can intervene to prevent many crashes caused by over-exuberant braking or throttle inputs. Without the IMU, TC and ABS cannot detect and then intervene to arrest traction loss that includes a lateral slide. With the lean-angle sensitive IMU, it can bleed engine torque or brake power if it detects abrupt changes in pitch, lean or direction. Cool, huh?

Disclaimer: The system I am reviewing here is the latest technology found on only a few 2014-2015 machines. Older and less sophisticated electronic aid packages without the benefit of a lean-angle sensitive IMU will not perform the miracles I am about to describe.

Testing, Testing: ABS

To test the traditional straight-line ABS I made several high and low speed runs on gravel and wet and dry pavement. The ABS never let me down. Riding on a wet tile runway with ABS switch off caused the bike to slam onto the sturdy outriggers with just the touch of the brakes. It was possible to apply the brakes without skidding, but it took all the brake feel and control I could muster. With ABS switched on, I was able to grab the brakes and the bike remained balanced on two wheels.

Riding on the gravel course further confirmed the effectiveness of the ABS as the bike to remained upright even when applying copious amounts of front brake pressure. Set to Enduro mode, rear brake ABS is disabled to allow direction changes using a locked rear wheel …fun, but not something I recommend on a 511-pound motorcycle with street-biased tires.

Testing, Testing: Cornering ABS

Testing the Cornering ABS (what Ducati calls Motorcycle Stability Control or “MSC”) required me to grab the brakes as hard as possible while fully leaned in a corner. Really?

It was nearly impossible to toss aside decades of instinctive emergency corner braking technique and common sense to do this test. Normally I would reduce lean angle before (or while) applying the brakes. Instead we were told to jam on the brakes and hold lean angle as long as possible.

Demo of Cornering ABS.
Demo of Cornering ABS. Bosch photo.

I held my breath and headed for the curve before I leaned hard and went for it. It worked! Not only did the MSC manage the available traction, it also allowed me to slow rapidly while maintaining the path through the curve; no more crossing into the oncoming lane or hitting a guardrail in an emergency corner braking situation.

Trying this on dry pavement was unnerving as hell, but a passing shower meant that I got the chance to test this mind-bending system in the rain. This maneuver went against all of my instincts but once I trusted the system I was sold!

Testing, Testing: Traction Control

After the MSC test, I set out to further tax my nerves by testing the Ducati Traction Control (DTC), which consisted of whacking the throttle open in second gear at 37+ degrees of lean. Instead of a nasty crash, the rear drifted controllably with the rear tire slipping and gripping predictably. Look at me, I’m Valentino Rossi.

But, the TC isn’t foolproof. During one run, I made a particularly abrupt throttle input while dragging the footpegs (crazy, right?) that caused the rear tire to swing a bit farther than comfortable, prompting me to instinctively reduce throttle enough to regain grip. The next time, I was determined to stay on the gas to see if the system would sort things out. I can’t be 100% sure whether I was a bit more cautious or the electronics reacted quicker, but this time the bike remained in control as I blasted out of the corner.

Smitten

At the end of the test, I was compelled to express my sense of awe with my friends on Facebook: “OMG. Bosch has defied physics with the corner ABS and Traction Control. I just grabbed a handful of front brake at 37 degrees and whacked the throttle WFO while dragging my foot peg IN THE RAIN!”

Debate

Somewhere in there are a bunch of electronic doo-dads that I hope can stand the test of time.
Somewhere in there are a bunch of electronic doo-dads that I hope can stand the test of time.

These electronics are awesome, but there are some valid concerns circulating about how traction and stability control is going to influence traditional methods and attitudes. Here are the major concerns and my responses:

  1. Reliability: Motorcycle electronics seem to be the Achilles Heel of reliability, so skepticism about reliability is understandable. But, consider that solid state technology has no switches, relays or moving parts to fail compared to mechanical devices, and connections are designed and tested to prevent dust and water infiltration. Also, other electronic units, like ride-by-wire throttles, have no cables to break. In the event that a fault does occur, “limp-home” mode will allow you to get home. Will it fail? At some point, probably. But will it render the bike useless, probably not.
  2. Electronic intervention will interfere when I don’t want it to: Older, less sophisticated systems have fewer options and have been known to get in the way. But, with the wide range of intervention levels to choose from with the latest systems, it’s hard to think there isn’t a setting that suits almost any rider. It’ll take time to really learn what these systems are capable of and to find your perfect setup.
  3. Electronics will interfere with the essence of riding a motorcycle: Contrary to what a lot of Luddites and Skeptics think, these systems can be set to lurk in the background, never impeding with normal riding situations. I believe these systems enhance riding and can be set to your liking to never (or rarely ever) get in the way of riding enjoyment.
  4. Advanced traction control make advanced rider skills obsolete: I don’t see rider technique becoming obsolete any time soon. To avoid close calls and crashes, riders must have strong control skills and effective survival strategies. You can still careen into a Buick or off a cliff, just like before. While TC will manage traction loss from clumsy braking and throttling, riders will soon learn that getting the most out of their motorcycle comes from smooth, well-timed rider inputs and not electronics.
  5. Electronic aids will encourage bad riding: It is possible that these electronics can encourage risky behavior as people discover just how competent these systems are. What’s to stop someone from relying completely on the TC to manage grip while powering out of a turn, or letting the ABS manage grip as he trailbrakes hard into a turn? TC and ABS may help prevent a crash, but will not to lead to better riding skill or faster lap times. Good technique still trumps electronic aids. Just ask the Moto GP guys. And remember, electronics cannot fix stupid.
  6. Electronic aids can lead to false confidence: Yes. I can personally attest that a false sense of confidence is possible. After fully testing the MSC, ABS and advanced traction control I was somehow fooled for one moment into thinking that the bike was not crashable. Of course, I was wrong! It’s important to remember that these systems manage available traction under braking and acceleration; they do not create more traction! You cannot expect to magically lean onto the edge of your tire over sand or dip into a corner over gravel and come out unscathed.

Despite looking like a Star Wars console, the Ducati interface is quite easy to use.
Despite looking like a Star Wars console, the Ducati interface is quite easy to use.

Safety

One of the most important selling points of the Bosch rider aids is safety. But, these systems cannot influence all crash factors, nor are they able to correct for bad decisions like excessive speed or bad lane position.

Riders must still rely on good technique and judgment to prevent most crashes from occurring. The smartest riders will never need these systems as they continue to use traction management techniques like smooth, progressive brake and throttle application.

Practice

Whether you have new-fangled IMU-based electronics or basic ABS, you should take time to practice maximum braking to the point where ABS kicks in. Without finding that limit, you will never trust that you can brake as hard as the system allows and not likely use the total amount of stopping power available when you need it most. Braking that hard is unnerving at first, but trust me the system will intervene.

4 Reasons Why You Need to Use Cornering Lines

Multiple corners require creativity.A “cornering line” is the path you follow around a corner. Riding a narrow, single-track vehicle means we are able to select the left, center or right positions within the lane. The “basic” cornering line starts by entering the turn at the outside edge of the lane and then continues to the inside or “apex” (near the middle of the corner), and ends with the motorcycle exiting toward the outside of the lane. This line is commonly known as the “outside-inside-outside” line. To learn more about the importance of road lanes, read this website: https://www.whiteliningcontractors.co.uk/.

Why Bother?

A lot of motorcycle riders don’t understand the benefits of cornering lines, believing that it’s good enough to simply keep their tires between the painted lines. This is fine when the road is predictable and speeds are low. But, as speeds increase and the road becomes more challenging, precise cornering lines become more important.

Cornering lines are a must when you ride on a racetrack, partly because the pavement is so wide that you would be silly to not use the available real estate. Riding from pavement edge to edge on the racetrack is the equivalent to using the whole width of the lane.

However, be smart! Don’t get too close to the oncoming lane or the outside edge of the road. Do not cross the painted lines (or lean into the opposite lane), but use the lane to your advantage.

Before we start, let’s define what an apex is. The apex is the “inside” point in the basic outside-inside-outside path of travel.

Here are the 4 primary benefits of riding cornering lines:

1. Straightens the Curve

Entering the curve from the outside, apexing near the inside and exiting toward the outside straightens the curve by increasing the corner radius, which requires less lean and preserves traction. It’s important to have traction in reserve in case you have to increase lean angle or execute a mid-corner maneuver.

By entering the turn wider and “apexing” around the curve, your bike will be pointed safely down the road at the exit. Apex too early and you’ll run wide.

2. Gives a Better Angle of View

This is the primary benefit for street riders. Entering a corner from the outside also allows a better angle of view into the corner so you can get an early look at the corner’s characteristics and identify any mid corner hazards so you can adjust your corner entry speed for safety.

3. Increases Cornering Confidence

Actively thinking about and choosing a deliberate path into a through curves makes you a Corner Master who rides with a plan. The result is a more preemptive attitude that puts your eyes, mind and body ahead of the corner.

4. Increases Cornering Enjoyment

Riding cornering lines increases the engagement you have with your bike–and every corner you encounter. Riders who unconsciously stay in the middle of the pavement are passive about their riding and miss out on the opportunity for deeper involvement.

 

DELAY your Turn-in

When you begin your turn (and how quickly you turn) has a significant impact on cornering precision and safety. New or nervous riders are anxious to get the turn over with, so they tend to turn in too soon. This places the bike at the apex too early, pointing the motorcycle toward the outside of the curve. To finish the turn and stay in the lane, the rider is forced to increase lean angle past the apex  at the time when they should be reducing lean angle. This is a common reason for corner crashes.

Not only does the delayed apex point the bike safely toward the corner exit and not at the outside edge of the road, but it also provides the best angle of view into the corner. Wait, wait, wait…now turn.

Quick Turn

To execute the delayed apex line requires a quick turn-in using firm countersteering. The harder you press on the inside handgrip, the quicker you will turn. Pull on the outside handgrip while pushing on the inside grip to turn in even quicker. Also, pre-position your body to the inside before the turn-in to help the motorcycle fall into the corner with even less effort.

Executing a precise cornering line requires coordination between the timing of your turn-in and the amount of countersteering intensity. Turning in too late and with not enough handlebar force can result in a “missed” apex, causing your motorcycle to stay in the middle or even outside portion of the lane, not near the inside as desired.

Sequential Corners

The basic outside-inside-outside cornering line is the obvious choice if the corner is isolated from other corners with a straight before and after the curve. But, multiple corners strung together can make the outside exit unusable and dangerous.

An outside exit that is appropriate for a single turn may prove too wide if the next corner bends in the opposite direction. In this situation, you have to ride an “outside-inside-INSIDE” line. This means you stay inside all the way to the exit where it becomes the entrance to the next corner. Depending on the relationship between corners, you may end up with an “outside-inside-MIDDLE” line.

Below is a video of Ken using cornering lines on a twisty road:

The trick to seamlessly stringing together a series of corners is to look well ahead  to identify each corner’s radius and determine what the proper entry is for the following corner. The best riders interact with their bike and the corners in a way that turns the road into a dance floor, making the mastery of cornering lines not only safer, but also very satisfying.

Do you use cornering lines?

Guest Writer: When Do You Lean?

The ability to lean a motorcycle with confidence is a fundamental part of riding. Unfortunately, humans do not come hardwired to lean much more than about 20 degrees, which is the lean angle where we start to lose traction  when we run in a circle on grass or dirt. Motorcycle riders must get beyond this lean angle limit for even basic maneuvers. This requires a leap of faith that the tires will grip. Practice is important to train your mind and muscles to lean beyond your comfort zone so you will be able to lean more if necessary. Once greater lean angles become more comfortable, the next skill to refine is timing so you reach maximum lean angle at the right point in the corner.

Meet Paul Duval

Paul Duval is the latest RITZ guest writer. Paul is a fellow track day and MSF instructor, former Loudon Road Racing Series 125 GP Champion, and professional educator. Let’s listen to Paul’s take on the importance of accurately timing maximum lean angle.


Timing Maximum Lean Angle

After many years of racing and instructing on the racetrack, there is one persistent mistake I see riders make when trying to ride faster: Using too much lean, too late in the corner.

Who is making this mistake?

Everyone is susceptible to this problem. Novice and intermediate track day riders often make the mistake of  increasing lean angle late in the corner in an attempt to get their knee down. Especially vulnerable riders are those with a lot of “natural talent” who got fast so much more quickly than everyone else. They end up riding fast, but without the knowledge and precision necessary to manage that corner speed.

What’s the Problem?

Adding throttle and increased lean angle at the same time is a bad idea.
Adding throttle and increased lean angle at the same time is a bad idea.

You may say, “What’s the big deal, I’m knee down and cranking?!” Yes, you may be fast, but this mistake WILL eventually lead to a crash, and probably a BIG one.

The problem with reaching max lean angle well after the apex of a turn is that this is precisely where you want to be on the gas.  Other riders will be already picking the bike up and driving hard.  This will encourage you to match their drive, but you are still adding lean angle.

Remember this:  Adding lean angle AND throttle at the same time is how high sides happen. The opposing forces of changing direction and accelerating can easily exceed available traction and will cause the rear tire to slide.   When this happens, slides are extremely quick, unpredictable, and hard to recover from.  All of your momentum is going exactly the wrong way.

Why do I keep doing this?

There are a few reasons people make this mistake.

Weak countersteering skills:  Newer riders haven’t yet mastered the “quick turn” technique of using counter steering to get the bike leaned over.  They bend their motorcycle into the turns gradually and often pass the apex entirely before the bike has changed direction.  Now they are running out of real estate and HAVE to lean it over to finish the turn.

Lack of reference points:Beginner and Intermediate track riders often use other riders as their reference points. This leads to a lot of crazy entry lines, none of which help the rider get the bike to change direction before the apex.  They commonly ride around the entry point as well as the apex, then crank the bike over to finish the turn.

Charging the corners:  Faster riders who make this mistake are at the most risk.  They rush into the corner at a pace that does not allow them to consistently hit their marks.  They will blow by a tip in point, drift wide past the apex, and then attempt to recover to get back on the “fast” exit line by adding a little more lean and a little more throttle.

Even with all this effort, they wonder why the faster guys are still pulling away.  They aren’t even cranked over like I am!!!  Hmmmm???  You may get away with late lean angles for a while, but eventually, you will push this mistake too far. Highside city.

The Solution?

The correction for all these riders is pretty similar.  And it’s not what they want to hear:  SLOW DOWN your corner entry to a speed that you can actually handle.  I mean a speed at which you can identify reference points, and ride an accurate line from tip in to apex that allows you to OPEN the corner after the apex, rather than tighten it up.  You need to learn to time your throttle inputs and your lean angle so that as you drive out of the corner and standing the bike up progressively as you roll on the gas.  BRAAAAP!  Wheee!


A quicker turn allows early direction change and less risk of an on-throttle highside.

Ken:

Thanks Paul. Paul mentioned the importance of being able to turn quickly. By being able to countersteer with authority, you are able to get your motorcycle from upright to leaned so that the majority of the direction change is complete BEFORE the apex. With the change in direction mostly complete, you can reduce lean angle as you roll on the gas. Traction is managed and all is well. Post your comments below.

Ground Clearance & Grip

Cornering on a big cruiser requires a respect for clearance limits.
Cornering on a big cruiser requires a respect for clearance limits.

I just received another letter from a Motorcycle Consumer News reader, this time about a situation he encountered when riding on a twisty back road in Cali on his Street Glide. Here’s his story, followed by my response.


“Ken, your recent article (in Motorcycle Consumer News) on cornering traction was excellent.  I just returned to Las Vegas after traveling up the coastal hwy to Oregon then back down to Las Vegas. While on that trip I had an incident involving cornering that left me very puzzled.

While heading to the coast from the 101 on hwy 128 north of San Francisco I was enjoying the curves of the coastal range. I ride a Harley Street Glide and ride fairly aggressively but not what I consider unsafe. As I was entering one turn (posted at 20mph) I leaned the bike into the turn and suddenly heard metal screeching on asphalt and almost simultaneously was aware that I had lost traction and was heading for the outside of the corner and a steep drop off.

Automatically I jammed my left foot down to the asphalt, but with my speed around 30-40mph sprained my ankle pretty badly. Much to my surprise I regained traction on the outside of the corner and was able to hold it there through the last 1/2 of the corner. My conundrum is that I’m not sure what happened! I felt comfortable with the speed I had entered the corner and I had entered from wide to just inside the center lane when the incident occurred. Normally, if I’m leaning the bike too much I’ll be aware of the foot board dragging. In this case there was no warning, just metal screeching and loss of traction simultaneously. Also, the road was great, with fairly new asphalt and no noticeable asphalt compaction or debris. Your thoughts would be greatly appreciated as this incident has made me extremely apprehensive whenever entering a corner with thoughts of this incident constantly in the back of my mind.”


Fairly aggressive cornering on a cruiser can be done, if you respect the bike's limits.
Fairly aggressive cornering on a cruiser can be done, if you respect the bike’s limits.

My Response

Without having seen or experienced the actual incident, I can only speculate on the cause based on knowledge of typical scenarios like yours. The fact is that ground clearance just doesn’t go from sufficient to nonexistent without a reason. It could be that you were leaning far enough that you were about to touch your floorboard when the mysterious factor occurred and your bike was suddenly grinding hard parts. This levered your tires off the ground and reduced traction.

Most times, when a bike suddenly goes from adequate ground clearance to zero ground clearance, it is a sign of traction loss caused by undetected surface contamination or debris, or abrupt throttle, brake or handlebar inputs, all of which are rider error. Sudden traction loss while the bike is leaned will cause the bike to drop quickly. This usually results in the rider tensing on the handlebars and chopping off the throttle, which exacerbates the problem.

If neither surface debris nor rider error existed, then you have to look at the possibility of a sudden and undetected change in surface camber that reduces ground clearance, or perhaps a depression in the road that would cause the suspension to compress.

Predicting that conditions can change quickly is a key survival strategy and applies to seemingly perfect pavement. New pavement can actually make ground clearance-robbing features such as undulations and dips difficult to see.

Knowing that your bike is a low slung machine means that you must be particularly sensitive and aware of these clearance hazards so that they don’t cause problems. One way to help manage limited ground clearance is to slow down.

Hanging off the inside of the bike helps increase clearance.
Hanging off the inside of the bike helps increase clearance.

You can also learn to use body positioning to help increase ground clearance. By simply dropping your head and shoulder to the inside, you shift the combined center of gravity of bike and rider so that your machine doesn’t have to lean quite as much. Practice this in a parking lot and notice that your floorboards don’t drag as readily. My book has drills that can help.

If you are riding briskly on your Street Glide and continue to have clearance problems, perhaps you are exceeding the limits of the bike and need to consider trading in for a model that is more suited to your cornering exuberance.

Now that we’ve discussed the possible cause, let’s look at your reaction. The sudden loss of ground clearance, for whatever reason, triggered a panic response that not only had no significant effect on allowing your big Harley to recover traction, but also caused you to injure your ankle. This panic response is part human nature and is how most riders react when faced with a potentially life threatening situation.

Off-road riding helps train for minor traction loss events.
Off-road riding helps train for minor traction loss events.

To minimize these survival instincts from causing more harm, you would need to re-train your mind and body to feel okay with minor traction loss. This is not easy to do when you ride a road-going cruiser, but is easily achieved with some off-road riding experience. Off-road riders routinely experience wide variations in traction and become accustomed to traction loss so that they do not overreact and make matters worse.

But, please understand that training yourself to react correctly is not a substitute for being aware of hazards and preventing them from causing an incident from happening in the first place.

The results of overriding a bike's capabilities can be disastrous.

I hope this helps.

Track Day Tire Dilemma

Modern sporty street tires are quite capable of fast track riding.
Modern sporty street tires are quite capable of fast track riding. I have street compound Corsa 3s on the ZX6 in this photo.

Tires can be a source of anxiety to a motorcycle rider. And it’s no surprise, since our tires provide us with the traction we need to make it home in one piece. When it comes to track days, many people use their only street bike to also ride on the racetrack. This is great because they learn the limits of the machine with which they spend the most time.

But, having a bike that is used for both street and track means compromising on certain things, one of the most important being tires.

Below is  a letter I received from a subscriber named Kevin from the UK. I replied to his email and hit the “Send” button, only to have it bounce back. Since this is a FAQ subject, I decided to post it for everyone to read. I am also hoping Kevin reads this reply, so that he knows that I am not ignoring his question.

The Question

Name    Kevin
Subject    trackday tyres – please help!

Hi Ken,
I have been searching the internet in order to get some advice re tyres when I stumbled upon your web site which has some great advice – you are clearly very knowledgeable, I wonder if you can help please? I own a 2006 GSXR 1000 K6 and have just booked a four day track day to Almeria in Spain in September, I need to buy tyres for this trip and am torn between either Supercorsa SP (so road compound) or SC compound (SC2 rear, SC1 front), can you help me decide which is best for me?

Here’s some information related to my situation: – I have participated in UK track days (but not since 2011) , I am generally at the front of the novice group or in the slower half of the intermediate group – I’ve never participated in a European track day before and wonder if the heat is a consideration (it will be around 75-80 degrees) – I used to have a dedicated track bike (only used for 1 track day!) which I ran an SC2 rear and SC1 front on but the GSXR 1000 is now my only bike, from now on it will spend 90% of it’s time on track with a small number of outings on the road Based on the above, do you think the SP (road compound) version of the Pirelli Supercorsa will be ok or would you recommend the track compounds and if so would you recommend an SC2 rear and SC1 front or SC2 for both front and rear? I’m worried the road version will lose grip due a combination of high ambient temperature and constant track use – does this sound feasible?

Based on your suggestion, how many track days do you think I will get from the front and rear tyre, would one front and one rear be ok for all four days or would I need two rear tyres and maybe two front tyres (the trackday is running three groups, 20 minute sessions so is not open pitlane). Would the road version last longer than the track compounds on track or would it be the other way around? This question sounds silly, but how can I tell when the tyres need to be changed? I’m scared that if the answer is to wait until they start to slide then I might crash!

I’ve never used tyres solely on track before so have changed them when they squared off but I realise this won’t happen on track so I’m not sure when I should change them – I want to get as much use as possible from them as they are very expensive but I don’t want to crash! Finally, I have a set of tyre warmers which I used on the SC2/SC1 combination, if you think the SP (road) version of the tyre will be fine, can I use the tyre warmers with them?

Thanks in advance for taking the time to read this, it’s very much appreciated, esp since we have never met and I found your details on line, apologies for having troubled you but this is literally making me lose sleep and you seem to have the knowledge and ability to give good advice.

Tire warmers are necessary for racing, but not for track days.

My Reply

Kevin,
Tires are a big source of stress even for seasoned track day riders. I have not seen you ride, but in your particular case, with the pace that is typical of a novice/intermediate track day rider, you could go with either Supersport street-oriented tires (Supercorsa SPs), or race compound tires (SC1 Super Soft/SC2 Soft).

It’s way easier to have a track-only bike so you don’t have to spend energy worrying about street versus race compound. But, realistically, street rubber is so good these days that you can push them pretty hard on the track and they will perform very well. Besides, novices do not typically need race rubber. However, as your pace picks up and you graduate to the faster ranks, street rubber will not perform well enough for sustained fast laps. That said, I have run advanced group laps on Pirelli Corsa 3 (Corsa Rosso) street-oriented tires with no troubles.

If your bike is going to be on the track 90%, then go for the SC2/SC1 combo. Although you could also go with the SC2s as I’m sure that they will be more than sufficient for your pace and may last a bit longer. The question is whether you want to use them on the street. A lot of people do use race compound tires on the street (often as “take-offs” discarded from racers), however you will wear them out pretty fast. And, you must be aware that race-compound tires will not heat up as quickly as the street-oriented SPs and will never get up to full temperature at street speeds. They may even provide less grip than street tires in normal street riding conditions.

If you find yourself riding more than 50%  on the street, I would consider moving to street rubber. But, once you become a solid intermediate track day rider you will want race rubber. The SP street compound will work, but want your tires to be better than you are whenever possible.

When it comes to tire warmers, they are nice but aren’t necessary, especially for street tires. Two laps at a moderate pace is enough to get them up to temperature. Even race tires don’t require tire warmers, but they do allow you to go fast after only a few corners. I do not use tire warmers at track days. I’m too busy working with customers to mess with them.

Too worn? The tire on the left still looks good, but it was starting to slide, so new rubber was mounted.
Too worn? The street-oriented Pirelli Corsa 3 on the left performed very well and still looks good, but it was starting to slide, so new rubber was mounted. Street rubber has it’s limits when you start going fast.

Deciding when to change tires is a stressor for most people. I did crash once after asking a front Corsas 3 to go one track day too many. The tire had endured a lot of abuse it wasn’t really designed for, so the punishment from too many hard laps caused them to not grip on a cold out lap. If I had just taken it a bit easier until they warmed up I would have been fine.

I tend to change front tires every 6 days and 4 for a rear, or earlier if the tracks I have ridden are particular abrasive. (I don’t know about Almeria).  That is after riding at all group levels with several expert track day laps thrown in. So, in my opinion, you will likely get the requisite 4 days out of both rear and front. Is there going to be a tire vendor at the track who can sell and mount tires if the tires are wearing faster than expected? Often there is. Find out so you can be prepared with tools and stands to change your tires at the track between days.

Good luck,
Ken

Getting Back on the Horse

In 14 years of riding I have, thankfully, only had a handful of crashes, and most were more embarrassing than anything else. Tip over’s at a stop or low speeds due to a patch of sand, a misplaced foot, etc. are common and happen to (almost) everyone in their early years. Even as a seasoned rider I recently tipped over my brand new Victory thanks to an unfortunate combination of factors. These things can hurt one’s pride, but for most we can walk away with minimal damage to self and bike, learn from our mistakes, and move on. These events are not what this post is about.

What I do want to talk about are two crashes, both of which occurred on the racetrack. The first one occurred during a track day on my 919, which was the result of a bad line that pushed me into an off-camber part of the track and left me with less than zero ground clearance, picking up my tires and putting me on the ground. The second occurred during a race in the rain when I crossed a paint line while trail braking into a corner and the front tire ran out of grip resulting in another low side.

Despite the obvious differences, there were many similarities between the two crashes. In both cases I was relatively unhurt and the damage to the bike was minimal enough to allow me to ride back to the pits. In both cases I knew exactly what I had done wrong (bad line, trail braking over wet painted markings) and how I could have avoided it.

The Aftermath

That’s the good news. The bad news is that I was left with a lasting reduction in confidence that I didn’t experience from my other get-offs. Why? Both occurred on a race track so perhaps it was the venue, though I’ve gone down on the track before and not had the same issue. And while the damage to the bike and my injuries were worse than a simple tip over, I’ve had worse mishaps that I was able to shake off. So what caused me to be so shaken up?

I believe the “when” mattered more than the “where” or “how”. You see, both crashes happened at the end of the day, which gave me no chance to get back out. Instead, I was left to wait until the next track day or race weekend to correct my mistake. This allowed my mind to endlessly replay the incidents over and over for days or even weeks.

Replaying the incident made a relatively minor crash grow into something much bigger and far scarier. When I finally did get back on track, it suddenly seemed like a dangerous place for me to be.

All of this was purely mental of course. By then I had largely recovered physically and the bike was mechanically sound. But because my mind was so clouded, my riding suffered horribly. Without realizing it, I began to fight myself in every corner, which caused me to keep running wide. To compensate I started braking earlier and crawling through the turns.

My muscles grew tired and sore within a couple laps from constantly working to keep the bike under control. My death grip on the bars left the front end feeling vague, leading to even less confidence. Each session left me more frustrated and exhausted than the last. Eventually I noticed what I was doing and began to relax and by the end of the day things seemed to be working properly again… And yet I was riding at a level far below where I had previously been. It took a great deal of time and effort to regain my lost mojo. Time and effort that could have netted some real gains were spent simply getting my confidence back.

The Takeaway

Which leaves me with this piece of advice for whoever cares to take it: The next time you drop your bike in a parking lot, lose your footing at a red light, or carry a bit too much speed at a track day and end up in the weeds, get up, get back on the bike and do whatever you just tried to do again, only this time do it right. Not only will you learn something in the process that can make you a better rider, but you will also retain your confidence before it has a chance to run off without you.


Thanks, Ian. The aftermath of a crash can be both physically and mentally scarring. I’ve seen countless riders lose confidence after a scare and either give up riding or not enjoy riding the way they had previously. While we cannot expect to avoid all mishaps, we can minimize them by riding within our limits (even when racing). Some say you have to crash to learn how to ride fast and win, but I don’t think it is a prerequisite. Yes, crashing comes with the territory of racing hard, but it usually sets you back and is generally a bad idea. You can learn to win without crashing, IMO.

You do this by learning all you can about traction and how a motorcycle stays on two wheels. This knowledge comes from many sources, including quality blogs, books, instructors and other skilled riders. But in the end, the secret to minimizing crashes is for you to apply this knowledge on every ride or race and develop sensitivity to the physics of riding well, at any speed.

Guest Writer: Track Day Rain Riding

Adam Butler is the first ever RITZ guest blog contributor. Adam is an expert level roadracer with the Loudon Roadracing Series and is one of my co-instructors for Tony’s Track Days. You can read Adam’s biography here

Let’s see what Adam has to say.


Do you like riding in the rain? I sure do!!

by Adam Butler

Adam Butler: "If you could see the smile inside my helmet".
Adam Butler: “If you could see the smile inside my helmet”.

If you ride track days on a regular basis chances are that you will find yourself presented with a rainy day. Some of us really find riding in the rain a fun and rewarding experience while others do not embrace the wet conditions as much. Some riders just don’t want to get wet. Others feel intimidated by the reduced traction available and don’t want to take a spill. I can understand the desire to keep your bike shiny and clean.  I prefer to take the chance to get out in the wet and work on my traction management. Riding in the rain presents a great opportunity to hone your smooth riding technique.

Ribbit!

There are some things that you can do to make your wet time on the track more enjoyable. The number one thing you need is a good frame of mind. If you go out with an open mind and a positive attitude you will have much more fun and success. It’s easy to have a fun, positive attitude in the dry…heck, we all love carving turns on a dry 70 degree day. Having this same outlook in the wet will make your experience much better.

Stay Dry and See

There are some gear related things that you can do to help. Some basic rain gear will help you stay dry. I have a basic Frogg Togg two piece outfit that goes over my leathers.

The last thing is to make sure your tires are in good shape. Any time you are on the track you need to make sure you have good quality tires. Dedicated rain tires are great but you can have a good time on street tires too.

Traction management in the wet all revolves around being smooth. When the conditions are wet there is less traction available. So naturally you will be able to get away with fewer mistakes. I start out slow and easy. I start my ride nice and easy and get a feel for the conditions. Then gradually increase my pace as my comfort level increases. The key is to stay relaxed. For me, that involves keeping a light attitude. I often will chat to myself or sing a little.

So next time it rains at a track day head out and give it a whirl. Just remember to bring your smile with you…. 🙂

How to Preserve Traction by Managing Load

The amount of traction depends on tires, pavement and load.
The amount of traction depends on tires, pavement and load.

Last weekend I conducted a seminar at the Thompson Speedway (in CT) and I thought I’d share a particular concept that came up during the presentation… the concept of “load management”.

When I first verbalized the term, I thought it sounded like the material for a crass poop joke. But, it is a concept I believe every motorcycle rider should adopt as a way to ensure that you have a sufficient amount of traction.

Traction Theory

Before I talk about specifics of load management, it makes sense to lay some theory on you. In its most basic form, traction is the friction between your tires and the road or track surface. This friction can vary greatly depending on several factors, including tire compound, condition and temperature, as well as the quality of the pavement surface (or dirt for you dualies out there).

Pavement texture affects the amount of traction available.
Pavement texture affects the amount of traction available.

But wait. The quality of your tires and the surface is only part of the traction equation. The other part is the amount of load that is placed on the tire’s contact patch. The more weight or load that each tire is supporting directly relates to the amount of grip each tire has. Additionally, using High Friction Surfacing on the road can enhance traction further, offering improved grip and safety, especially in challenging conditions.

Practical Application

When you brake, the front suspension compresses as the weight of rider and bike pitches forward. This increases front tire traction. But, at the same time, the rear suspension extends and the load (and traction) at the rear tire decreases. More traction on the front means you can use the front brakes harder. But, it also means that there is less load at the rear and therefore less rear tire grip for hard use of the rear brake. Load shifts constantly with every maneuver you make…braking, cornering, swerving, accelerating etc.

Loads also shift with the terrain. Riding uphill shifts weight rearward. Riding downhill moves the load to the front. Riding over bumps also causes momentary shifts in load and changes in traction. Road camber also affects load.

Managing Your Load

If you grab the front brake, you'll skid the front tire.
If you grab the front brake, you’ll skid the front tire.

So, managing traction requires you to manage the location and amount of load. This means making sure your front tire is sufficiently loaded before you introduce maximum front brake force. Squeeeeeze the front brake lever. It also means easing off the rear brake as load pitches forward when you brake. The key is to apply the brakes only as much as the tire can handle, which means paying attention to the amount of load there is on each tire.

Now, too much of a good thing is too much of a good thing. In this case, you can overwhelm the front tire while braking and skid. However, if you squeeze the front brake progressively then you should not have this problem. If you grab the brake, then you risk locking the front wheel.

Managing traction while cornering downhill requires balance between speed control and acceleration.

You can also overwhelm and push the front tire into a lowside skid when cornering hard. To avoid this, you need to get on the throttle just after you initiate lean to balance load between the front and rear. If you coast through the turn, you’re asking the front tire to not only manage the cornering forces, but also the engine braking forces caused by not getting on the gas.

The amount of throttle used should be just enough to transfer load to the rear tire. Do this by gradually rolling on the throttle. DO NOT twist the throttle to the stop or you’ll overwhelm the rear tire and spin it out of control.

The best riders are keenly aware of the amount of traction they have available at any given time. They also use advanced techniques that minimize abrupt spikes in load and allow the tires to maintain grip.Some of these techniques include brake and throttle overlap, trailbraking, and advanced body positions that allow the suspension to work fluidly.

Start by paying attention to how load affects traction, then move on to developing these advanced techniques for load and traction management. I’ll write about these techniques in future blog posts, but you can read about them now by ordering your copy of Riding in the Zone.

How to Develop a Traction Sense

Most people don’t think how much traction management is a part of almost every moment of our lives. Walking, driving, and even showering all require a certain level of traction management. We don’t always think of these mundane things as tasks that require “traction”. But, our brains are constantly calculating whether our footing is secure enough to prevent us from slipping in the shower, or sliding down stairs, or careening off the road.

Traction Senses

Having enough available traction is critical for safely riding a motorcycle. But, are you as sensitive about your tire’s traction level as you are the traction level of your footing when you step into a shower? Most people would have to answer “no”.

That’s partly because when you are riding a motorcycle, the interface between your nerves and the ground is insulated by tires, suspension, a frame and a seat. When you’re standing in the shower the nerves in your feet are almost directly connected to the tub so that it is easy to tell whether the surface has enough grip to not slip. If you’re not sure, you simply move your foot along the surface to determine whether you must take extra care.

Once you’re out of the shower and dressed, your shoes separate the bottom of your feet from direct contact with the floor, which adds a level of complexity when determining traction. In this case, we rely more on the whole nervous system to tell whether our shoes have enough grip or not.

Your proprioceptive senses are the senses that communicate with your brain and muscles to keep you safe. Proprioceptors tell you about the relative position of body parts and strength of effort being used as you move. They are located in your muscles and joints and help you perceive your body in space. A slight slip will trigger your proprioceptive senses to tell your brain and muscles to react to regain balance.

Riding stiff in low traction situations is a bad idea.

Get a Grip

On a motorcycle, you must develop the ability to sense whether your tires have enough grip on the road for you to remain upright. But, how is this possible?

First, you must learn to “read” the information being delivered by your motorcycle’s tires and chassis. Your bike’s components are speaking to you through the language of slip angles and aspects of balance that include roll, pitch, and yaw. As your bike leans, dives and squats, your nerves are calculating whether your bike is in balance and on the intended path or at the beginning of a loss of control.

A relaxed posture allows clear communication between you and your tires.

You feel this through the footpegs, handgrips, and seat. Keeping firm, but relaxed contact with the grips and pegs and riding with a relaxed posture will allow the best transference of information between your tires, the suspension and your nervous system.

Everyone who rides has a traction sense, otherwise we would never be able to trust that we would make it out of our driveway, let alone negotiate corners at speed. A rider who is able to manage less-than-ideal traction situations is highly proficient at sensing what the tires are doing. The information is there, you just have to listen.
