NAMURA . NX-20000

Namura pistons are made to exact OEM specifications and are direct replacements for OEM pistons with no modifications or dimensional adjustments needed Piston kits come with the piston(s) individually wrapped, a set of OEM quality rings packed in their own box, wrist pin(s), and circlips Namura pistons have MOS2 (Molybdenum/Teflon) skirt coatings, high-silicon aluminum and anodized domes A, B and C pistons are available to help extend the life of expensive Nikasil, SCEM, Boron Composite and Ceramic Cylinders Namura rings are made by Riken, the world's largest OEM manufacturer and are the same OEM rings used on more motorcycles and ATV's than any other brand

Bore: 53.94mm Sizing: Standard Bore MOS2 (made with Teflon/Molybdenum) Coated Skirts - A rolled on application process provides a fits Bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures. Machined Smooth Heads - Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%. Anodized Domes - Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons. Hypereutectic Casting Process - Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures.
