Description
The WSM Piston Kit for Yamaha 350 is engineered to deliver reliable performance that meets or exceeds OEM specifications, making it the ideal choice for riders who demand durability without compromise. The advanced MOS2 coating on the skirts actively reduces friction and heat while drawing thermal energy away from the piston crown—translating to improved power delivery and extended piston life. With a specially hardened crown and refined E-clip design, this kit provides the precision fit and longevity you need whether you’re rebuilding a stock engine or refreshing a high-mileage powerplant.
