PISTON KIT 86-96 CR250 67.00, WOSSNER 8021D060 HONDA MX

Wossner Forged Piston Kit 67.00mm Bore – Honda CR250R (1986–1996)
This Wossner forged piston kit is engineered for Honda CR250R models from 1986 to 1996, with a bore size of 67.00 mm and a piston diameter of 66.94 mm (+0.60 mm oversize). Ideal for use in significantly overbored cylinders, this forged piston provides high structural integrity and optimised thermal conductivity. The elliptical design distributes stress evenly across the piston surface, reducing wear and the risk of failure. Manufactured in Germany to meet high precision standards.
