HONDA CR250R 1986 - 1996,
Namura Piston Assembly - 66.4mm Bore - A NX-10026
High-performance Namura pistons are engineered in the USA, manufactured in Taiwan 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 and heat 56-W614.A.PX the art CNC equipment. The same low-expansion, low-friction piston alloy is used as is used for all major Japanese engine manufacturers. ProX Piston Kits are a first class solution to replace the original piston in your Motorcycle, Scooter, Moped, ATV, Personal Watercraft, etc.
Coated for ultimate performance Most of the ProX pistons come with a coating. Our OEM style Tin coated pistons assist the wear in process when you just started the bike. We have

power and longevity Namura rings match the OEM design except as noted -B (.0004 in.) and -C (.0008 in.) fractional oversize pistons, available for some applications, extend the life of your expensive cylinder by renewing the original clearance if it's slightly worn, avoiding an expensive sleeve installation Piston assemblies include ring(s), wrist pin and circlips
