WOSSNER 67.5mm FORGED PISTON KIT B, KTM 250 SX 1995

Wossner forged piston kit with a 67.51mm bore (67.45mm actual) is specifically developed for KTM GS250 and SX250 models from 1995. Crafted in Germany, this piston features an elliptical profile that distributes thrust loads evenly and supports optimal heat transfer from the combustion chamber to the cylinder wall, reducing stress concentrations and minimising the risk of piston failure under thermal expansion.

Features

• High-strength forged piston construction

• Designed for efficient combustion heat dissipation to cylinder wall

• Elliptical shape promotes consistent bearing surface under expansion

• Prevents localised stress points and piston deformation

• Precision manufactured in Germany
