Ive done a trackday at infineon years ago on a ktm motard. Too many places for the big bikes to stretch their legs, where im stuck at 95-105 mph depending on gearing... Id recommend buttonwillow for hyper owners over all the tracks in north/central california. The cart track u mentioned sounds interesting!Thanks, that helps a lot actually.
I live very close to Sears Point (Infineon) and there's a world class go-kart track above the big track that they run Supermoto on every week, I think it's like $60.
I may try a track day on the small track before running on the big track, even though all my past experience is on the big track. I think it will be fun.
I'm sure I'll run into someone there who can give me some tips.
