This Wossner forged piston kit features a 57mm bore (56.94mm actual) and is designed for use in the Kawasaki KX125 (1986). Built for high performance and reliability, the piston offers efficient combustion heat transfer and an elliptical profile to distribute thrust loads evenly. This design minimises stress concentration and helps prevent piston collapse. Manufactured in Germany, this +1.00mm oversize piston kit is compatible with 2-stroke specifications and includes the necessary matched components.
