I am guessing your talking about the big track at willow or streets turned plenty of laps on both. Horse Thief mile I don't think your busa would hold up to these machines. Not necessarily with me riding on it but with a skilled pilot. Whole new type of riding to learn. That's why I got it.That a supermoto bike? Far from a Busa beater. I see those things ALL THE TIME at my track day events. I smoke em in the twisties. Never saw them in the straights b/c I would usually leave em far behind in the twisties.
However, I do want one b/c I wanna learn that powerslide technique that the MotoGP guys perfected. Too crazy to learn that on Busa.
