## Complete Piston 73.70mm Namura NA-20005-4 - Performance and Reliability The Namura NA-20005-4 piston kit is an excellent way to improve the performance and reliability of your motorcycle or ATV engine. This complete kit offers precise fit and high-quality workmanship, characteristic of the Namura brand. The 73.70mm diameter piston with a 1.00mm oversize is an ideal solution for engines requiring regeneration, giving them a new lease on life. ### Advanced Technologies for Maximum Performance Namura utilizes advanced technologies in the production of its pistons, which translates into tangible benefits for the user. The MOS2 (Teflon/Molybdenum) coating on the piston skirt reduces friction and improves heat transfer, minimizing the risk of cold seizures. The smooth, machined piston crown reflects combustion heat and reduces carbon buildup, which increases power and reduces fuel consumption. The anodized coating on the piston dome increases resistance to high temperatures and ensures longer life. ### Hypereutectic Casting for Durability The hypereutectic casting process used in the production of the Namura NA-20005-4 piston ensures higher silicon content, reduced thermal expansion, and additional wear resistance. This guarantees long-lasting and trouble-free engine operation. ### Complete Kit Ready for Installation The Namura NA-20005-4 piston kit includes an individually wrapped piston, a set of OEM quality rings, a wrist pin, and circlips. The 1.00mm oversize refers to the difference between the nominal piston diameter and the cylinder diameter in which it operates. ### Benefits of Choosing a Namura Piston: * **Increased engine performance and reliability** * **Extended engine life** * **Savings on replacement costs** * **Precise fit and high-quality workmanship** * **Advanced technologies for maximum performance**
