The 55mm Bore Wossner Piston Kit (Part No. 8067D100) is a +1.00 oversized forged piston designed for Honda CR125 models from 2000 to 2003. Manufactured in Germany, it features an elliptical profile that evenly distributes thrust loads and minimises stress concentrations caused by heat expansion. This piston is optimised for two-stroke performance with efficient heat transfer characteristics and structural reliability under high-load conditions.
