Wossner forged piston kit with a 97.02mm bore and 96.98mm diameter, designed for KTM SX-F450 models. This high-compression piston (13.50:1) 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.
