PISTON KIT YZF450 14-15 97.00, FORGED WOSSNER 8895DA, 1SL-11631-00-00

Wossner forged pistons are engineered for enhanced strength and optimal thermal conductivity, facilitating efficient combustion chamber heat transfer to the cylinder walls. The elliptical design ensures a uniform bearing surface during thermal expansion, minimizing localized stress and evenly distributing thrust loads to prevent piston collapse. This 97.00mm bore piston (96.96mm actual size) is designed specifically for high-performance Yamaha engines and is manufactured in Germany.
