## Complete Piston 102.97mm Namura NA-10012-4 Boost the performance and reliability of your motorcycle or ATV with the Namura NA-10012-4 complete piston kit, featuring a 102.97mm (+1mm) diameter. This high-quality piston kit offers an excellent alternative to original equipment manufacturer (OEM) parts, providing significant cost savings compared to replacing the entire cylinder. ### Superior Quality and Durability The Namura brand is synonymous with precision and reliability. The NA-10012-4 piston is manufactured using hypereutectic technology, characterized by a high silicon content, resulting in reduced thermal expansion and increased wear resistance. The anodized piston crown further enhances high-temperature resistance and extends service life. ### Reduced Friction and Improved Heat Dissipation The piston skirt is coated with MOS2 (Teflon/Molybdenum), which minimizes friction, improves heat transfer, and prevents cold seizures. The smooth, machined piston head reflects combustion heat and reduces carbon buildup, contributing to increased horsepower and fuel economy by up to 6%. ### Complete Kit Ready for Installation The Namura NA-10012-4 piston kit includes an individually wrapped piston, a set of OEM quality rings, a wrist pin, and circlips. The +1mm oversize refers to the difference between the nominal piston diameter and the cylinder bore it operates in. ### Benefits: * Increased engine performance and reliability * Extended engine life * Cost savings compared to cylinder replacement * Reduced friction and improved heat dissipation * High-quality manufacturing and materials ### Specifications: * Piston Diameter: 102.97mm * Oversize: +1mm * Brand: Namura
