Namura Pistons & Accessories

As a wise man once said, you can’t start a fire without a spark, and your machine needs a great piston in order to spark a fireball of performance. Since 2001, Namura Technologies has been working tirelessly from their Minnesota headquarters to produce pistons, rings and accessories for modern riders. Not content with the “overpriced paperweights” flooding the market, Namura uses innovative designs and the latest manufacturing techniques to produce components that outperform their stock counterparts while costing less. With Namura pistons from Dennis Kirk for dirt bikes, ATVs and UTVs, your engine will have the spark that ignites unmatched performance.

Engineered in the U.S. and manufactured in ISO-certified facilities in Taiwan, Namura pistons are built to do more at every step. Each piston is made from high-silicone cast aluminum, with crowns that are machined smooth and then anodized for hardness. This creates a piston that has tighter clearances with reduced heat expansion, wear and carbon buildup for more horsepower and better fuel economy. Even the skirts are designed for power and longevity with a MOS2 coating that reduces friction. A Namura piston assembly includes piston rings, a wrist pin and circlips for installation and tuning. You can also order sets of Namura piston rings for rebuilds, repairs or to use with new pistons.

Whether you use your machine to run circles around motocross competition, go for day rides in the backwoods or do work around your property, Namura pistons will help you do it better and more reliably. To find the piston assembly or rings that match your ride’s engine, enter its information into our fitment tool or search by bore size. Our Tech Team is also available for expert assistance. With the lowest guaranteed prices and free same-day shipping if your order exceeds $89, Dennis Kirk and Namura make it easy for any rider to afford a great piston for their engine.
