PISTON KIT 86-88 YZ125 56.00, WOSSNER 8118DA YAMAHA MX 1LX-11635-00-00

Wossner 56.00mm Forged Piston Kit for Yamaha YZ125

This Wossner 56.00mm standard bore forged piston kit is engineered for high-performance two-stroke engines. Manufactured in Germany, its forged construction provides superior strength and durability. The innovative elliptical design ensures a uniform bearing surface even during heat expansion, effectively managing thermal stresses and promoting even mechanical load distribution. This design helps prevent localized stress buildup and potential piston collapse, contributing to reliable engine operation. The piston is optimized for efficient heat transfer from the combustion chamber directly to the cylinder walls, aiding in temperature management.
