This Wossner piston kit features a 91.00mm bore size (90.92mm actual) and is designed for Honda CR500 (1984–2001) and CR480 (1982–1983) models. Manufactured in Germany, the forged piston offers high strength and efficient thermal management. The elliptical design ensures uniform distribution of thrust loads during thermal expansion, minimising localised stress and reducing the risk of piston failure.
