Upgrade your engine with the NAMURA Top End Kit Twin Cylinder, designed for optimal performance and durability. This comprehensive kit includes a high-quality piston, rings, wrist pin, clips, top end bearing, and gasket set, providing everything needed for a complete top-end rebuild. The piston features MOS2 (Teflon/Molybdenum) coated skirts, applied through a rolled process that creates a bond ten times stronger than typical spray coatings. This coating enhances heat transfer, reduces friction, and helps prevent cold seizures, ensuring smoother operation and longer engine life. The machined smooth heads reflect combustion heat more efficiently and reduce carbon buildup, which can improve both horsepower and fuel economy by up to 6%. Anodized domes further bolster heat resistance and durability, with pistons featuring anodized domes that are 75% stronger than non-anodized options. The hypereutectic casting process used in manufacturing increases silicon content, reducing expansion rates and providing exceptional wear resistance, enabling the piston to withstand higher cylinder temperatures. This kit is engineered to deliver improved engine performance, longevity, and reliability, making it an ideal choice for enthusiasts seeking a high-quality upgrade. Suitable for engines requiring a bore size of 92.97 mm with a +0.02 mm oversize, it ensures precise fitment and optimal function. Trust NAMURA’s expertise in engine components for your motorcycle or small engine rebuilds, and experience enhanced power and efficiency with this top-end kit.
