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

This Wossner forged piston kit is intended for Suzuki RM250 models from 1996 to 1997 and features a 68.02mm bore (+0.02mm oversize). Manufactured in Germany, it incorporates a precision-engineered elliptical design that evenly distributes thermal expansion stresses across the bearing surface. This reduces localised pressure and prevents piston collapse. The piston supports efficient heat transfer from the combustion chamber to the cylinder wall, enhancing engine stability and longevity in high-performance two-stroke applications.
