PISTON 96-97, 99 RM250 66.40, WOSSNER 8058DB SUZUKI MX

This Wossner forged piston kit is manufactured for Suzuki RM250 two-stroke engines from 1996 to 1997 and features a 68.01mm bore (+0.01mm oversize). Crafted in Germany, the piston utilises an elliptical design to manage thermal expansion, evenly distributing load and reducing the risk of collapse. It enhances heat transfer from the combustion chamber to the cylinder wall, supporting consistent engine operation in demanding conditions.
