Upgrade the performance and reliability of your Polaris engine with the Namura Standard Piston Kit, a premium replacement designed for both stock and modified motors. Engineered for precision and durability, this 92.95 mm piston kit delivers exceptional strength, heat resistance, and reduced friction—ensuring your Polaris operates at peak efficiency in even the most demanding conditions.
Manufactured using an advanced hypereutectic casting process, the Namura piston features a high silicon content that minimizes expansion rates and increases wear resistance. This makes it ideal for engines that run under high temperatures or experience heavy workloads. The anodized dome design enhances durability by providing 75% more heat resistance compared to non-anodized pistons, allowing for a longer service life and improved performance consistency over time.
Each piston is equipped with MOS2 (Teflon/Molybdenum) coated skirts, applied using a rolled-on process that creates a bond ten times stronger than standard spray coatings. This reduces friction, improves heat transfer, and helps eliminate cold seizures during startup. The machined smooth crown reflects combustion heat, reduces carbon buildup, and can improve both horsepower and fuel efficiency by up to 6%, making this kit a smart investment for serious riders.
The Namura piston kit includes everything needed for a complete installation—piston, rings, pin, and circlips. It replaces Polaris part numbers 2205244 and 2204948, ensuring a perfect fit and hassle-free compatibility. Whether you’re rebuilding your engine or upgrading for better performance, this kit delivers consistent power, smoother operation, and extended engine longevity.
