The NAMURA NX-70047K Top End Kit is a comprehensive solution designed for KTM motorcycles, featuring a Nikasil-coated cylinder for enhanced durability and performance. This kit includes a piston, rings, wrist pin, clips, top end bearing, and gasket set, providing all essential components for a complete top-end rebuild. The Nikasil coating ensures a smoother surface and reduces wear, extending engine life and maintaining optimal performance over time. Ideal for riders seeking to restore or upgrade their engine's top end, this kit delivers increased efficiency and reliability.
Constructed with advanced materials and manufacturing techniques, the piston features MOS2 (Teflon/Molybdenum) coated skirts. This rolled-on application provides a bond that is ten times stronger than typical spray coatings, resulting in improved heat transfer, reduced friction, and assistance in preventing cold seizures during startup. The machined smooth heads reflect combustion heat efficiently and help minimize carbon buildup, which can enhance horsepower and fuel economy by up to 6%, according to some tests.
The anodized domes increase heat resistance and durability, making the piston 75% stronger than non-anodized alternatives. Additionally, the hypereutectic casting process incorporates higher silicon content, reducing expansion rates and boosting wear resistance. This allows the piston to withstand higher cylinder temperatures, ensuring long-lasting performance even under demanding riding conditions. Overall, the NAMURA NX-70047K Top End Kit offers a high-quality upgrade for KTM enthusiasts seeking improved engine performance, longevity, and efficiency.
