PISTON KIT 02-04 CR250 66.40 B, NAMURA NX-10027-B HONDA CR250
Namura Piston Assembly - 66.40mm Bore - B NX-10027-B. High-performance Namura pistons are engineered in the USA and manufactured in Taiwan using high-silicon content hypereutectic cast aluminum material for less heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing. Features machined, smooth piston crowns for reduced carbon buildup, increased horsepower, and fuel economy. Hard anodized crowns are 75% stronger than non-anodized, providing minimal expansion and reducing the chance of cold seizures when combined with Teflon/Molybdenum coated skirts. MOS2 (Teflon/Molybdenum) coated skirts perform at the highest standards, reducing friction. Namura rings match OEM design. Fractional oversize pistons, available for some applications, extend the life of your cylinder by renewing the original clearance if it's slightly worn. Piston assemblies include ring(s), wrist pin, and circlips.
