Mine was a 1982 Kawasaki KX250. Thing was continually falling apart. Base Gaskets Blew on a regular basis. Frame slowly gained rake...as is bent..making it handle more like a wheel barrow than a motorcycle. Forks literally broke. Countless clutches. The thing was a true POS bike. But I loved that disk brake! Had to have one. A trip to the emergency room from the seat of that bike put an end to serious racing in my life. (Probably for the best)
