Why replace your cylinder when you can replace the piston for a fraction of the cost and time? Namura offers direct replacements for the original equipment as well as hi-compression and a variety of oversizes to meet your ride’s needs. They are available in 0.25mm increments, from the -1 (0.25mm) through the -8 (2mm) oversize. Namura also carry B (0.01mm) and C (0.02mm) oversizes which help extend the life of your expensive coated cylinders; a selection of big bore piston kits is available for some applications. Combine this with the MOS2 coating and hard anodizing, Namura gives you a higher performance piston without the higher price.

Namura piston kits come with the piston individually wrapped; a set of OEM quality rings packed in their own box, a wrist pin, and circlips.

MOS2 (Teflon/Molybdenum) Coated Skirts
A rolled-on application process provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction, and helping to eliminate cold seizures.

Machined Smooth Heads
Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%.

Anodized Domes
Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons.

Hypereutectic Casting Process
Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures.

Namura® Technologies offers a wide variety of pistons, rings, gaskets and bearings for today’s MX, ATV, UTV and Off-Road riders. Namura extensive line-up features applications for Arctic Cat, Can-Am, Honda, Kawasaki, KTM, Polaris, Suzuki, Yamaha and most other models. By pushing the envelope of conventional standards, Namura strive to provide a superior product using the latest advancements in manufacturing techniques. Keeping that in mind, Namura didn’t want to be an overpriced paperweight supplier. Namura philosophy is simple: deliver superior engine components that have more features than the OEM at a better price.
