Your cart is empty.Namura Top End Kits come with the piston(s) individually wrapped, a set of OEM quality rings packed in their own box, wrist pin(s), circlips and a top-end gasket set. Namura pistons are made to exact OEM specifications and are direct replacements for OEM pistons with no modifications or dimensional adjustments needed. Namura pistons have MOS2 (Molybdenum/Teflon) skirt coatings, high-silicon aluminum and anodized domes. 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. A, B and C pistons are available to help extend the life of expensive Nikasil, SCEM, Boron Composite and Ceramic Cylinders. Namura top-end gasket sets include head, base and other necessary gaskets, O-rings and valve guide seals, as required, to complete a top-end rebuild.
