For this old guy it is my CBR 600 F4, it was set up for the track originally when it was new by a AMA racer as a track play toy, it all the work was done to the best quality. I have been fortunate enough to have Dave Moss around at several track days I have atteneded, and he has continued to refine the suspesion for my riding style.
You were my coach at Level I on 4/1, and that little bike I can put anywhere on the track and get superb feedback as to what it is doing.
When the front end starts to push, add a bit of throttle and the rear accepts the load transfer. When the back end steps out it never wants to just rev up to 5000 rpm faster than what I am holding, but just gets a grip, so not to worried about a high side.
I own several Aprilia bikes, but I have no desire to ride them on the track as this little bike is just too honest. Neat thing on the technical tracks such as SOW, Thunderhill, etc. I don't give up anything except at the very end of a straight to a liter bike.
I am a happy camper.
