Benefits include increased heat transfer, reduced friction, and helping to eliminate cold seizures.Machined Smooth HeadsReflects 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 DomesIncreases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons.Hypereutectic Casting ProcessProvides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures.2002 - 2021 Suzuki RM 85 Top End Rebuild Piston Kit
