Wossner forged piston kit with a 77.01mm bore and 76.97mm diameter, designed for Suzuki RM-Z250 models (2010-2014). This high-compression piston is engineered for superior strength and optimized heat transfer. Its elliptical design provides a uniform bearing surface under heat expansion, reducing localized pressure and evenly distributing thrust loads to prevent piston collapse.
