a warrior that has run on the track is still in tip top shape if maintained properly. pretty much the bike is indistructable. i ran mine at the drag strip about 20 races one day and did no noticable damage not even to the clutch. got my oil changed when i returned home and still looked brand new. being a month later(and and a new rear tire) bike is still running like a champ and i have no concerns for the future....
