This Wossner forged piston kit with a 55.25mm bore is an oversized (+1.50mm) replacement for the Sachs 125/7 engine. Manufactured in Germany, it delivers excellent strength and heat transfer performance. The elliptical piston design ensures even pressure distribution during thermal expansion, reducing localised stress and enhancing durability in two-stroke engine applications.
Features
Forged construction for superior strength and longevity
Engineered for efficient combustion chamber heat dissipation
Elliptical profile maintains consistent bearing surface under thermal load
Even distribution of thrust loads minimises piston stress and wear
