Namura Piston Assembly NX-10026-C for Honda CR250R 1986-1996. Features 66.40mm bore with C fractional oversize. Engineered in the USA and manufactured in Taiwan, this piston uses high-silicon content hypereutectic cast aluminum for reduced heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing. Machined, smooth piston crowns reduce carbon buildup for increased horsepower and fuel economy. Hard anodized crowns offer 75% greater strength than non-anodized, minimizing expansion and the risk of cold seizures. MOS2 (Teflon/Molybdenum) coated skirts reduce friction and heat, ensuring high performance and longevity. Namura rings match OEM design. Fractional oversize pistons (-B and -C) are available for some applications to extend cylinder life by renewing original clearance on slightly worn cylinders, avoiding expensive sleeve installation. Piston assemblies include ring(s), wrist pin, and circlips. Weight: 340g.
