Rebuilding the top-end of your 100cc engine with this Namura Performance kit is the most effective way to restore lost compression and snap. Specifically sized at 52.46mm (+0.02), this "B-series" piston is engineered for cylinders that have seen standard wear, allowing for a tighter seal and better performance than a standard A-size piston. When you are ready to buy a Namura Piston Kit, this all-in-one solution provides everything needed for a professional-grade overhaul.

This Kawasaki KX100 replacement piston kit features MOS2 (Teflon/Molybdenum) coated skirts and an anodized dome for maximum heat resistance. Whether you are prepping for a race or a weekend at the trails, this KX100 top end service kit utilizes a hypereutectic casting process to withstand higher cylinder temperatures and reduce expansion. The result is a more durable engine that resists carbon buildup and maintains power longer than traditional cast pistons.
