Description
If you’re rebuilding or refreshing your Kawasaki 750 engine, piston quality directly impacts reliability, power output, and engine longevity. WSM’s +.50mm piston kit delivers OEM-matching construction with performance-oriented refinements—particularly the MOS2 coating on the skirts, which reduces friction and heat while actually drawing thermal energy away from critical ring grooves. This is a complete, ready-to-install solution that eliminates sourcing individual components.
Order one kit per cylinder to ensure consistent performance across all bores.
