JE Pistons Ring Sets 0.9-000-1.5-3.150

If you're rebuilding the top end of your 2006-2009 Kawasaki KX250F, these JE Pistons ring sets are a solid choice for getting your engine sealed up right. They're built to maximize horsepower by precisely sealing combustion pressure, which is key for getting the most out of your engine. JE Pistons offers these in a wide variety of sizes and materials, and they even provide custom services like back cutting and PVD coating, similar to what top racing teams use, to improve durability and reduce friction.

This particular set features a 0.0354-inch stainless steel nitride top ring and a 0.0591-inch stainless steel nitride low-tension oil ring. The stainless steel nitride construction helps ensure good sealing and durability, while the low-tension oil ring is designed to reduce drag for improved performance. These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation, which is standard practice for performance builds.
