I think I see where you're coming from. I have never crashed my STREET bike on the track, but let me tell you, when your daily ride (944 Turbo) nails the Budweiser sign @ PIR, (cough cough) you can bet that insurance covers it.
But really, at a trackday, I wouldn't worry about crashing your bike. Most insurance companies are pretty good about track mishaps as long as there is no cash prize at the end of it.
Track days are not race days. Ride at the speed you feel comfortable with. Don't get involved with the sqiuds who think that a track day is a RACE day. Just go at your own pace, and you'll be okay. If you have any other questions about track performance, etc. call me @ 480.430.6362.
