This Wossner forged piston kit with a 51mm bore (50.95mm) is designed for the 1984 Honda CR80R. Manufactured in Germany, the piston enhances durability and thermal efficiency. Its elliptical design provides uniform load distribution during expansion, minimizing localized pressure and reducing the risk of piston collapse.
