PISTON KIT 90-94 KTM250 67.50, WOSSNER 8005DB FORGED

Wossner Forged Piston Kit 67.51mm Bore for KTM 2-Stroke Engines

This Wossner forged piston kit is engineered for high-performance 2-stroke motorcycle engines. Featuring a precise bore size of 67.51 mm and a piston diameter of 67.45 mm, this kit is designed as an oversize replacement for enhanced engine power and longevity. The forged construction offers superior strength and durability compared to cast pistons, ensuring reliable operation under demanding conditions.

The piston's elliptical design is a key feature, promoting even thrust load distribution across the cylinder wall. This advanced geometry minimizes localized stress and reduces wear, even during rapid expansion and contraction cycles caused by extreme temperatures. This results in smoother engine operation and extended component life.

Manufactured in Germany, each Wossner piston kit adheres to rigorous engineering standards, guaranteeing exceptional quality and performance. This kit is ideal for enthusiasts seeking to optimize their motorcycle's power output and engine reliability.
