PISTON KIT 85-86 RM125 55.00, WOSSNER 8123D100 SUZUKI MX
PISTON KIT 85-86 RM125 55.00, WOSSNER 8123D100 SUZUKI MX
This Wossner forged piston kit features a 55.00mm bore with a +1.00 oversize specification and is designed for Suzuki RM125 models from 1985 to 1986. Produced in Germany, the piston incorporates an elliptical design that promotes even distribution of thrust loads during thermal expansion. This reduces the risk of localised pressure and piston collapse while supporting efficient heat transfer from the combustion chamber to the cylinder wall.
