Description

The Wossner 8114D100 piston kit features a 57.00mm bore (actual 56.94mm) and is designed for exceptional strength and optimised heat transfer to the cylinder walls. The forged, elliptically designed piston ensures a uniform bearing surface during heat expansion, minimising localised pressure and evenly distributing thrust loads to prevent piston collapse. Manufactured in Germany, this kit includes essential components for reliable engine performance and is compatible with Yamaha YZ125 models from 1990 to 1993.

Features

Forged piston construction for enhanced strength and durability
Engineered for efficient combustion chamber heat transfer
Elliptical design provides uniform bearing surface under thermal expansion
