Description
Description
This Wossner forged piston kit is developed for the 1997 Yamaha YZ125 and features a 56.00mm bore (+2.00mm oversize). Precision-engineered in Germany, it is designed with an elliptical profile that optimises load distribution and reduces localised stress during heat expansion. This construction enhances durability and prevents piston collapse under high-performance conditions. The kit promotes effective heat dissipation from the combustion chamber to the cylinder wall, ensuring stable engine performance in demanding two-stroke applications.
