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

Wossner forged piston kit with a 67.50mm bore (67.44mm actual) is designed for KTM GS250 and SX250 models from 1995. This piston offers exceptional strength and thermal efficiency, utilising an elliptical design that provides a more consistent bearing surface under thermal expansion. Manufactured in Germany, it reduces localised pressure and evenly distributes thrust loads to protect against piston collapse during operation.

Features

• Forged for high strength and durability
