Description
When you’re pushing a Kawasaki 220 to its limits, factory pistons become your bottleneck. The WSM Piston Kit delivers OEM-quality construction with engineered improvements—MOS2-coated skirts that actively dissipate heat, hardened ring grooves that withstand aggressive compression, and an optimized E-clip design for reliability under sustained load. Whether you’re rebuilding after a hard season or upgrading for added displacement, this kit gives you the durability and performance margin that separates consistent racers from those chasing repairs.
