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.
Features
Forged construction for superior strength and durability
Designed for efficient heat dissipation from combustion to cylinder walls
Elliptical design provides a uniform bearing surface under thermal expansion
Even distribution of thrust loads reduces localised pressure points
Manufactured in Germany
