## Namura Complete Piston 91.958mm NA-80001-4 - Performance and Reliability This complete Namura piston with a diameter of 91.958mm (with +1mm oversize piston) is a great way to improve the performance and extend the life of your motorcycle or ATV engine. The Namura brand, known for its high-quality parts, offers a replacement for the original piston that guarantees reliability and optimal performance. ### Advanced Technology for Maximum Performance The use of innovative technologies in the production of the Namura piston translates into real benefits for the user: * **MOS2 coating (Teflon/Molybdenum):** Reduces friction, improves heat transfer, and prevents cold seizures, ensuring smooth and efficient engine operation. * **Smooth, machined head:** By reflecting combustion heat and minimizing carbon buildup, it contributes to increased horsepower and fuel economy by up to 6%. * **Anodized dome surface:** Provides increased resistance to high temperatures and extended piston life. * **Hypereutectic casting:** Contains a higher silicon content, which reduces thermal expansion and increases wear resistance. ### Complete Set Ready for Installation The set includes an individually wrapped piston, a set of OEM quality rings in a separate package, a piston pin, and circlips. The +1mm oversize piston refers to the difference between the nominal piston diameter and the cylinder bore it operates in. ### Benefits of Choosing a Namura Piston: * Improved engine performance and reliability * Extended engine life * Savings on replacement costs * High quality guaranteed by the Namura brand ### Professional Installation It is recommended that the installation of the Namura piston be carried out by a qualified mechanic.
