Namura Piston Kit 1.50mm Oversize 84.44mm Two-Stroke ATV For Sale - New and Used

Namura Piston Kit – 1.50mm Oversize to 84.44mm (Two-Stroke)

• MOS2 (Teflon/Molybdenum) Coated Skirts: A rolled-on application process provides a bond reported to be 10 times stronger than spray-on coatings, offering increased heat transfer, reduced friction, and help in eliminating cold seizures.
• Machined Smooth Head: Reflects combustion heat and reduces carbon buildup to protect the top of the piston. Some tests indicate this feature can increase horsepower and fuel economy by up to 6%.
• Anodized Dome: Increases heat resistance and durability; pistons with anodized domes are reported to be 75% stronger than non-anodized pistons.
• Hypereutectic Casting Process: Provides higher silicon content for reduced expansion rates and additional wear resistance, with an ability to withstand higher cylinder temperatures.

Note: Will not accept stock rings and rings will not work on stock piston.
