I recently did my first trackday at Cadwell recently (Bike magazine, road legal bikes only), it was great fun and I really enjoyed it. I did it on my ZX7R as opposed to my GS1200, just because it seemed more suitable and I dont use it as much as I should now that I have the GS. I started off a little nervously but was soon holding my own (overtaking as much as I was being overtaken) and felt that my corner speed was fine. The bikes that were reguarly getting past me were a couple of GS1200's and a bloody Triumph tiger. this seemed to be mostly aproaching and exiting corners, probably because I am braking to early and using poor lines that have me hugging the corner and accelerating too late. At my novice level it seems obvious to me that rider skill is more important than what you bike use. I would be wary about taking the GS on to the track, just because of its value, if I ever take up track riding seriously then I would probably look at a cheap SV650 or ER6 that I can learn with and find my limits on, and if I chuck it, it wont be the end of the world (then I may consider doing some sports bike humbling on the GS).
