Upgrade your Husqvarna or KTM engine with the NAMURA NX-70020-BK top end kit, designed to enhance performance and durability. This comprehensive kit includes a high-quality piston, rings, wrist pin, clips, top end bearing, and gasket kit, providing everything needed for a complete rebuild or performance boost. The components are engineered to meet the demanding specifications of modern motocross and off-road riding, ensuring reliable operation and long service life.
All parts feature advanced coatings and machining processes to optimize heat transfer and reduce friction. The piston skirts are coated with MOS2 (Teflon/Molybdenum), a rolled-on application that bonds ten times stronger than conventional spray coatings. This coating helps to improve heat dissipation, minimize cold seizures, and extend piston life. The machined smooth heads reflect combustion heat effectively, which can lead to increased horsepower and better fuel efficiency—some tests have shown gains of up to 6%.
The pistons are equipped with anodized domes that improve heat resistance and durability, making them 75% stronger than non-anodized options. The hypereutectic casting process used in manufacturing provides higher silicon content for reduced expansion rates and enhanced wear resistance. This process also allows the piston to withstand higher cylinder temperatures, making it suitable for aggressive riding conditions. Whether rebuilding or upgrading, this top end kit offers a reliable solution for maintaining peak engine performance with a focus on longevity and efficiency.
