Description
Whether you’re rebuilding a tired Sportsman 500 or stepping up compression for added trail performance, a quality piston kit is non-negotiable. The Wiseco 4677M09200 delivers the strength and precision needed to handle sustained high RPMs and aggressive riding conditions. This complete kit eliminates guesswork—rings and circlips are included, so you can focus on the install rather than sourcing compatibility parts.
Wiseco’s high-silicon alloy construction provides the durability required for both stock and modified engines, resisting detonation and thermal stress better than cast alternatives. The 92mm bore and 10.2:1 compression ratio are purpose-built for the Sportsman 500, ensuring proper fitment and predictable power delivery across the RPM range.
