Keith,
I've read Twist Of The Wrist II many times and have been a fan of the book for awhile now. I've been a trackday only rider for the past 3 years(just started round 3) Previously I mainly rode my 01 Honda F4I, in fact it was my very first motorcycle ever and all I ever rode on the track(besides a few of my friends bikes here and there). Last year on my F4I I was around 2:07 @ T-hill and around 1:55 @ Infineon(best laps not necessarily consistent times). As a little background info I had my F4I's suspension geometry setup with a lot of Rake which made it steer effortlessly. It is a very twitchy bike but due to the nature of its geometry it made it very very easy, in fact I would even say necessary to late apex. If I didn't take a very deep late apex line, the bike would steer to the apex so quickly that I would end up early apexing so I adopted this whole late apex, quick turn strategy. Having a bike like this really helped me identify with many of the techniques that you described in your book.
What I didn't realize is that when I stepped up to my new trackbike things would change drastically. I recently bought a 05 Honda 600RR and its a great bike. The problem is that it feels completely opposite. IT steers like a friggin tank, yes its stable midcorner like no other bike I've ever ridden but getting it to initiate turn-in, and leaning it, and reaching the apex is very difficult for me. So far I'd done 4 trackdays this year(Infineon, T-hill, and Buttonwillow) and I'm just having a really hard time.
No longer can I change my line midcorner or have complete control of the bike with the push of the bars. On this bike If I pick the wrong line there is no margin for error. No matter how much body steering I use the bike just does not lean very easily and even worse does not want to change its direction without using a lot of time. I've been trying to slow down, set my entry speed, and concentrate on steering the bike quickly yet still keep my same lines which are a late apex followed by a strong drive. Its just not working, it seems I have to "arc" this bike into the turn, it just takes a lot more time to get the bike down to the ground and leaned over. I immediately realized I had to start turning in early to reach my apex to avoid running wide out of the turn (by missing the apex completely)
I have been playing with the suspension, geometry, and many other factors which are helping, but I feel that this bike no matter what I do is not adapting to this style of riding. In fact I'm starting to feel that part of the key is to start needing to traibrake more to get the frontend to dive and reduce the trail to turn quicker and as well scrub speed to make sure the bike gets down to that apex. Saying that, I do recognize that you can't do that on every turn, and there will still be turns where I need to let off the brake and just use my body/arms to try and snap the bike over.
So what do you recommend? Do you feel that certain types of bike require different styles of riding? I'm gonna take a big fat guess and assume that you might recommend possibly going even slower till I can achieve the correct supsension setup combined with the correct steering technique until I can ride it like my ole F4I. Maybe I just need to keep trying but its really not working for me. HElp!
