Now that I’ve ridden the 2013 Aprilia Tuono V4 APRC for a full season of track days, I feel it’s time to share some thoughts. You can read about the modifications I did and the accessories I installed HERE.
First thing I learned is how to ride the bike the way it wants to be ridden. Don’t fight your bike, learn about its wants and needs.
1. The Tuono turns in great, but doesn’t hold a line mid corner without some effort. To remedy that, I need to get a lot of weight over the front end. Much better. I ended up lowering the front end (by sliding the forks up by 3mm in the triple clamps, which cured much of the mid corner effort.
2. The Tuono feels a bit cumbersome at half pace. Like a lot of harder edged sportbikes (and race set ups), it can be tough to get the Tuono to change direction (even with the tall bars). However, pick up the pace and all is well. Also, lowering the front helped. as well.
3. The stock suspension is soft, even for my 150 pound physique. Thanks to Peter Kates from GMD Computrack Boston for adjusting the Sachs suspension to the best it’s going to get. A lot more preload helped settle the bike in the fast transitions. But, even though the suspension is “busy”( moves around at full lean over sustained bumps). I’d surely need to spend some bucks on better boingers if I want to go much faster with less effort.
4. I tend to drag my boots in corners with mid-corner bumps. Not becasue of low footpegs, but becasue of the soft suspension. More preload and more aggressive body positioning helped.
5. If you have not ridden a liter bike at a track day, then you probably haven’t had to think about “big biking” people who are on slower bikes whose rider is faster in corners. It’s courteous to be aware that you may be holding up someone. Be kind and ease up on the straight every once and a while.
6. The Tuono puts down about 150hp. That’s great, but having power can fool you into thinking you’re fast. Sure, my overall lap times are better, but my corner speed is about the same as on the 130hp GSXR and even the 95hp Street Triple.
7. High handlebars suit my riding style. I never felt as comfortable on the GSXR as I have on the Street Triple or the Tuono. Riding a high handlebar bike fast requires you to hold the inside grip like a screwdriver to allow your upper body and elbow to dip low inside for the most effective body position.
8. Tire wear has been surprisingly good. I thought the bike would eat rear tires, but it’s been fine. I strive to be smooooth and the Tuono gives me more confidence to open the throttle early so I spread the drive over the whole edge-to middle part of the tire, instead of lifting before triggering the 150 hp. See photo.
9. Traction control is quite abrupt. I was exiting turn 3 at Thompson Speedway when I thought the chain had jumped a few sprocket teeth. It turns out I had inadvertently hit the TC button located on the left control pod and increased the setting to 5, causing intervention. I thought this indicated a spent rear tire, but putting it back to the less intrusive #3 out of 8 (1 being least intervention), the tire was fine.
10. The Arrow exhaust (with db insert) sounds amazing. But, it’s rather quiet compared with a lot of other track bikes. And I’m okay with that. The V4 still sounds like a hot rod.
