PISTON KIT SACHS 125/7 54.25, WOSSNER 8287D050 PIN 16mm

This Wossner forged piston kit with a 54.25mm bore is an oversized (+0.50mm) replacement for the Sachs 125/7 engine. Manufactured in Germany, the piston is designed for strength, longevity, and efficient thermal performance. Its elliptical profile ensures even expansion and pressure distribution, reducing the risk of piston failure in two-stroke applications.
