Description
OEM-equivalent pistons are the foundation of reliable engine performance, and WSM’s piston kit delivers the durability and precision your Yamaha engine demands. The MOS2 coating on the skirts actively reduces friction and heat transfer, translating directly to increased power output and extended component lifespan.
