This Wossner forged piston kit with a 54mm bore (53.94mm) is designed for Suzuki RM125 models from 1981 to 1984. Precision-engineered in Germany, it enhances engine durability and thermal efficiency. The elliptical piston design allows for consistent bearing surface during thermal expansion, effectively distributing loads and minimizing the risk of piston collapse.
