Piston Kits
Namura
Namura Piston Kits W hy 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. We 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. N amura piston kits come with the piston individually wrapped; a set of OEM quality rings packed in their own box, a wrist pin, and circlips.
Namura N Forged 4-Stroke Piston Kits N amura Forged pistons offer dyno-proven gains in performance and durability over industry-standard 4032 forged pistons. Namura’s exclusive forged alloy offers lower expansion rates, allowing for tighter build tolerances and superior tensile and yield strength at operating temperatures. A ll new Forged pistons come with Namura’s signature features: 100% CNC-machine piston domes, hard anodized domes for reduced carbon build-up and heat resistance and M0S2 coated skirts for excellent break-in protection and properties.
