FULL DESCRIPTION
Wossner 66.4mm Domed Twin Ring Forged Piston Kit
This Wossner forged piston kit is engineered for exceptional strength and performance in demanding 2-stroke motorcycle engines. Designed for optimal heat transfer, it efficiently moves heat from the combustion chamber to the cylinder walls, contributing to consistent performance. The innovative elliptical design ensures a uniform bearing surface even under extreme heat expansion, effectively reducing localized pressure and distributing thrust loads evenly to prevent piston collapse. Manufactured in Germany to high standards, this piston is built for durability and reliability.
