Namura's Top End kit is ideal for replacing worn parts and making some upgrades. Machined Smooth heads, available for certain models, can increase horsepower and fuel economy while reducing carbon buildup.

  • Top End kit includes: piston, rings, wrist pin, clips, top end bearing, and gasket kit
  • MOS2 (Teflon/Molybdenum) Coated Skirts - A rolled on application process provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures
  • Hyperdryve pistons are composed of a new hypereutectic aluminum alloy developed for use in the space industry
  • Engineered to maintain its high tensile strength up to 700�F
  • This revolutionary alloy, combined with our already existing features of machined smooth anodized heads (for better heat reflection) & MOS2 coated skirts (giving you smoother startups & break ins) meets the demands of today's 4-stroke engines.
  • 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
  • Piston Size: 96.97mm
  • Images are for reference purposes only
