I used ST tire at the track, it was not an issue. I dont think going to a more sport oriented tire would of made a difference since the bike didnt have the lean angle to begin with, and neither does it have the power to lose grip that much.
Never mind the dirt marks, i crashed out this day, dont worry, its because i lifted the rear end on the kickstand, not cause i lost traction!
Anyway, this is the tire not pushing it too much on a normal 80degree day. It doenst wear funny or anything. Its perfectly fine for the track, i put about 400 miles of track time on it
