Namura Technologies Top End Repair Kit

Namura Technologies piston kits are direct replacements for OEM piston with no modifications or dimensional adjustments needed. Combine this with the MOS2 coating and hard anodizing, Namura gives you a higher performance piston without the higher price.

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.

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.

Top End Repair Kit includes:
  • Piston
  • Rings
  • Top end gasket kit
  • Bearings where needed
  • Item # 53809

This rebuild kit is very easy to install, but it has it's doubts with me. I had it put on my dirt bike for 3 weeks and after 3 weeks of riding it messed up, the gaskets fit perfect, and I had no problems with installation.
