Overview

The Namura NA-50081 is a piston kit designed for powersports applications. This kit features pistons constructed from hypereutectic aluminum, known for its reduced expansion rates and higher resistance to wear and cylinder temperatures. The piston crown is machined smooth to reflect combustion heat and minimize carbon buildup, while also being hard anodized for increased heat resistance and durability. A MOS2 coating is applied to draw heat through the piston walls and out the bottom, further enhancing performance and longevity.

This piston kit includes pistons, rings, circlips, and wrist pins. Namura offers direct replacements for original equipment, as well as options for increased compression. The piston's construction aims to provide higher performance without a significantly higher price point, offering a reliable solution for engine rebuilds.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
