Namura Atv Piston Kit Yamaha

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
