Description

Wossner Forged Piston Kit 66.41mm 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 66.41 mm and a piston diameter of 66.35 mm (+0.01 mm oversize), it is designed for use in cylinders requiring a minor oversize piston. The forged construction enhances strength and thermal efficiency, while the elliptical shape ensures even load distribution and reduces the risk of piston collapse. Manufactured in Germany to exacting standards.

Features

Forged piston for superior mechanical strength and longevity
Designed to facilitate optimal combustion heat transfer to the cylinder walls
Elliptical geometry ensures uniform pressure distribution and reduces wear
