Description

The Wossner piston kit 8114DB features a 56.01mm bore (+0.01 oversize), tailored for Yamaha YZ125 two-stroke engines manufactured from 1990 to 1993.

The elliptical design allows uniform expansion under heat, reducing stress points and improving overall piston integrity. Precision-made in Germany, this component is suited for both competition and high-demand recreational use.

Features

Forged construction ensures superior strength and long-term durability
Heat-optimised design facilitates effective combustion heat dissipation
Elliptical shape maintains a uniform bearing surface during expansion
