Upgrade your engine with the NAMURA NA-50093K top end kit designed for twin cylinders with a 90.42cc displacement and standard polarity. This comprehensive kit includes a high-quality piston, rings, wrist pin, clips, top end bearing, and gasket set, providing all essential components for a complete overhaul or upgrade. Engineered for durability and performance, the kit ensures your engine runs smoothly with reliable compression and power output.
Features like MOS2 (Teflon/Molybdenum) coated skirts offer a bond that is ten times stronger than traditional spray-on coatings, significantly reducing friction and enhancing heat transfer. This coating helps prevent cold seizures, ensuring consistent engine operation even under demanding conditions. Machined smooth heads reflect combustion heat efficiently and minimize carbon buildup, which can lead to improved horsepower and fuel economy by up to 6%. Anodized domes increase heat resistance and strength, with anodized pistons being 75% stronger than non-anodized alternatives, adding to the longevity of your engine components.
The hypereutectic casting process used in these pistons incorporates a higher silicon content, reducing expansion rates and offering superior wear resistance. This ensures the pistons can withstand higher cylinder temperatures without deforming, maintaining optimal performance over time. Whether you're restoring an older engine or building a new one for performance, the NAMURA Top End Kit provides durable, precision-engineered components that meet high standards of quality and reliability.
