Description

This Wossner forged piston kit with a 90.04mm bore (+0.04mm oversize) is designed for all Speedway applications, including GM Speedway 499cc engines. Precision-forged in Germany, the piston features superior strength and optimal heat transfer capabilities. Its elliptical profile promotes uniform pressure distribution and expansion under thermal load, minimising stress and reducing the risk of piston failure.

Features

Forged construction for maximum strength and performance
Engineered for efficient heat dissipation from combustion to cylinder walls
Elliptical profile ensures consistent bearing surface under expansion
Reduces localised pressure and evenly distributes thrust loads
Manufactured in Germany
