Key Features:

• MOS2 (Molybdenum/Teflon) Coated Skirts — Applied via a roll-on process that bonds up to 10 times stronger than spray-on coatings. Improves heat transfer, reduces friction, and helps prevent cold seizures during initial startup.
• Machined Smooth Piston Heads — Reflects combustion heat away from the piston crown and minimizes carbon buildup. Testing has shown this feature may improve horsepower and fuel economy by up to 6%.
• Anodized Domes — Enhances heat resistance and overall durability. Anodized domes are approximately 75% stronger than non-anodized counterparts, extending piston life under high-stress conditions.
• Hypereutectic Casting Process — Higher silicon content results in reduced thermal expansion rates and greater wear resistance, allowing the piston to withstand elevated cylinder temperatures without compromising integrity.

The Namura NA50012CK top end kit is a trusted choice for powersports engine rebuilds, combining advanced piston technology with a complete hardware and gasket set to simplify the repair process and restore reliable engine performance.
