PISTON KIT 96-99 KTM250 67.50, WOSSNER 8016DA FORGED

This Wossner forged piston kit is specifically designed for KTM MXC250, EXC250, and SX250 models from 1996 to 1999. With a 67.50mm standard bore, it delivers the structural reliability required in high-performance two-stroke engines. Manufactured in Germany, the piston features an elliptical profile that accommodates thermal expansion, ensuring uniform load distribution and reducing stress concentrations. This design enhances piston longevity and supports efficient heat transfer from the combustion chamber to the cylinder wall.

Features

• Forged piston construction ensures high durability and mechanical strength

• Elliptical design distributes bearing surface load evenly under thermal expansion

• Prevents localised stress points and minimises risk of piston collapse

• Engineered for optimal heat transfer from combustion chamber

• Precision-manufactured in Germany
