Wiseco Piston Kit Kawasaki KLF220 Bayou 1988-2002 PK1047

If you're running your Kawasaki Bayou hard, factory pistons won't cut it. The Wiseco Piston Kit PK1047 is engineered to handle sustained high RPMs and extreme operating temperatures while delivering the reliability you need to finish the race or trail ride. This complete top-end kit gives you everything needed for a professional-grade rebuild without sourcing components piecemeal.

Wiseco's forged high-silicone construction minimizes thermal expansion, keeping your engine stable under load and preventing the ring-to-wall clearance issues that plague stock rebuilds. The included forged piston, matched rings, wrist pins, circlips, and gasket are precision-engineered as a system—each component designed to work in concert for maximum efficiency and longevity. Installation is straightforward for experienced mechanics with proper tools; this is a bolt-in upgrade for your KLF220 top-end.

Critical Note: Always use genuine Wiseco rings with Wiseco pistons. Mixing brands or using worn OEM rings will compromise performance and void the integrity of your rebuild.
