WSM Piston Kit - Kawasaki - +.5 mm 010-821-05K

When you're pushing your Kawasaki to the limit, OEM pistons become a liability. The WSM Piston Kit delivers OEM-equivalent quality with meaningful upgrades—particularly the MOS2-coated skirts that actively dissipate heat and reduce friction, translating directly to improved power output and extended piston life. Whether you're rebuilding after a failure or prepping for sustained high-RPM operation, this kit gives you the durability and performance characteristics serious riders demand.

The enhanced E-clip design and specially hardened ring groove tops add robustness where it matters most, while the included piston, rings, pin, and clips provide everything needed for a complete installation—order one kit per cylinder.
