This VintCo top end piston kit is for Honda CR250 models from 1978 to 1980 and is supplied as a complete rebuild set for a 71.5 mm, +1.5 mm overbore top end. The kit includes a forged piston, rings, pin, clips, a top end bearing, and a full top-end gasket set with head, base, intake and exhaust gaskets. Components are manufactured using modern materials and production methods for OEM-equivalent fitment and performance.
