Description
If you’re rebuilding a 2-stroke JS650, you need pistons engineered to handle the extreme heat and pressure cycles that stock components simply can’t sustain. Wiseco’s high-silicone forged piston kit delivers the durability and precision ring fit that separates a reliable rebuild from one that leaves you stranded. This complete kit includes everything you need—pistons, rings, wrist pins, circlips, and gaskets—so you’re not hunting down individual components and guessing at compatibility.
