The NAMURA NX-70004K Top End Kit is designed to enhance the performance and durability of your KTM motorcycle with a 46.95mm Nikasil cylinder. This comprehensive kit includes a piston, rings, wrist pin, clips, top end bearing, and gasket kit, providing all essential components for a complete top-end rebuild. Crafted with precision, the piston features MOS2 (Teflon/Molybdenum) coated skirts, which through a rolled-on application process create a bond that is ten times stronger than conventional spray-on coatings. This coating improves heat transfer, reduces friction, and helps prevent cold seizures, making your engine run smoother and more reliably. The machined smooth heads reflect combustion heat more effectively and reduce carbon buildup, which can boost horsepower and fuel efficiency by up to 6%, offering noticeable performance gains. Anodized domes increase heat resistance and durability, with pistons that are 75% stronger than non-anodized options, ensuring longevity under demanding conditions. The hypereutectic casting process used in manufacturing provides a high silicon content for reduced expansion and enhanced wear resistance, allowing the piston to withstand higher cylinder temperatures. Designed for serious riders and enthusiasts, this top end kit delivers a combination of strength, heat management, and efficiency, making it a reliable upgrade for your KTM motorcycle.
