Description

This Wossner forged piston kit is developed for the 1997 Yamaha YZ125, featuring a +0.01mm oversize with a 54.01mm bore. German-manufactured and built for high-performance two-stroke engines, this piston is engineered with an elliptical design to manage heat expansion evenly. It minimises localised pressure, distributes thrust loads uniformly, and supports efficient heat transfer to the cylinder walls, reducing the risk of mechanical failure and improving engine reliability.

Features

Forged piston construction for high strength and durability
Elliptical shape distributes pressure evenly under heat expansion
Prevents piston collapse and enhances structural stability
Supports efficient combustion heat dissipation
Precision-crafted in Germany
