Namura Technologies NA-50002-6 Piston Kit Hypereutectic Coated - 84.5mm MOS2

The Namura Technologies NA-50002-6 is an 84.5mm piston kit engineered for high-performance reliability and durability. Built using a hypereutectic casting process, this piston kit delivers superior wear resistance, reduced thermal expansion, and the ability to withstand elevated cylinder temperatures — making it an excellent upgrade or replacement choice for demanding powersports applications.

Key Features:

• MOS2 (Teflon/Molybdenum) Coated Skirts — Applied via a rolled-on process that bonds up to 10 times stronger than spray-on coatings, improving heat transfer, reducing friction, and helping prevent cold seizures during startup.
• Machined Smooth Heads — Reflect combustion heat away from the piston crown and minimize carbon buildup. Testing has demonstrated potential gains of up to 6% in horsepower and fuel economy.
• Anodized Dome — Enhances heat resistance and structural durability; anodized domes are approximately 75% stronger than non-anodized counterparts.
• Hypereutectic Casting — Higher silicon content reduces expansion rates and increases wear resistance, allowing the piston to operate reliably at higher cylinder temperatures.
• 84.5mm Bore Diameter — Precision-machined to tight tolerances for proper fitment and optimal ring seal.

Namura Technologies piston kits are designed as direct-fit replacements and typically include the piston, piston rings, wrist pin, and circlips (contents may vary by application). Whether you're performing a top-end rebuild or a performance upgrade, the NA-50002-6 delivers OEM-quality engineering with enhanced durability features.
