Namura . NX-40025KA

Namura piston kits with gaskets include everything you need to restore the top end of your bike to factory fresh specs. The kits are complete with pistons, rings, and all gaskets and O-rings needed to complete a top end rebuild. Piston kits are precision machined to Japanese OEM specifications, using low-expansion, low-friction piston alloy resulting in an extend life span of the piston. Our Teflon coated skirts uses a rolled-on application process which provides a bond that is 10 times stronger than other spray on coatings. Gaskets use materials such as Stainless Steel, Fluoroviton and Teflon. Namura gaskets are made to exact OEM specs but with better materials to last longer and keep your bike running stronger.

Bore: 66.35mm<br>Compression: 10.9:1 Compression<br>Sizing: Standard Bore<br><br>Top End kit includes: piston, rings, wrist pin, clips, top end bearing, and gasket kit.<br> 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.<br> 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%.<br> Anodized Domes Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons.<br> 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.<br> Ceramic Composite Cylinder
