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. 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 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.

Piston isn't true it's egg shaped at the thrust point, Wrist pin wouldn't fit in the piston wasn't even close had to use the old wristpin, also didn't come with a wrispin bearing. Very dissatisfied!!! Now the only way to fix my cylinder is to buy a new cylinder can't go any larger in bore.
