Description
A worn or damaged piston directly compromises your SX500R’s combustion efficiency, throttle response, and engine longevity. The Wiseco SK1163 kit restores—and exceeds—OEM performance with precision-forged components engineered specifically for 2-cycle reliability under sustained high-rpm stress. This comprehensive top-end solution eliminates the guesswork of sourcing compatible rings, pins, and gaskets separately.
Wiseco’s high-silicone alloy construction minimizes thermal expansion, meaning your engine maintains consistent compression and sealing across the entire operating range, from cold starts to full-throttle conditions. The kit’s design philosophy prioritizes durability without sacrificing the responsive power delivery your machine demands.
