Wossner forged piston kit with a 100.01mm bore and 99.96mm diameter, designed for KTM SMR560 models. This high-compression piston (12.00:1) enhances performance and durability. Manufactured in Germany, it ensures optimal heat transfer to cylinder walls. Its elliptical design provides a uniform bearing surface under heat expansion, reducing localized pressure and evenly distributing thrust loads to prevent piston collapse.
