Namura NA-40006-4 / 79-40006-04 Kolvsats Yamaha Big Bear 400 +1mm
(1st kolv)

Namura-kolvarna har teflonyta som minskar friktion och kolvens överhettning.
Kolvens topp är anodiserad, som märkbart minskar upphettningen av kolven.

Features:

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.
