This Wossner piston kit features a 55.25 mm bore size and is designed for high-performance compatibility with the Suzuki RM125 models from 1985 to 1986. Manufactured in Germany, the piston is forged for enhanced strength and reliability. It is engineered to optimise heat transfer from the combustion chamber to the cylinder walls and features an elliptical design that improves bearing surface uniformity under heat expansion. This design helps distribute thrust loads evenly and prevents localised pressure and piston collapse.
