Namura NX-20013-BK 48.46 mm Top End Kit for Kawasaki KX85

Upgrade the top end of your Kawasaki KX85 with the Namura NX-20013-BK Top End Kit. Designed for 2014–2020 Kawasaki KX85 models, this kit includes the essential components needed for a reliable piston replacement and top-end rebuild. The kit includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit for convenient installation and dependable engine service.

The Namura piston uses a hypereutectic casting process with increased silicon content to help reduce expansion, improve wear resistance, and withstand higher cylinder temperatures. Its MOS2 Teflon and molybdenum-coated skirts use a rolled-on application process that creates a durable bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. The 48.46 mm piston size and 11:1 compression configuration are engineered for the specified Kawasaki KX85 application.

A machined smooth head helps reflect combustion heat and reduce carbon buildup, supporting piston protection, performance, and fuel efficiency. The anodized dome enhances heat resistance and durability, with greater strength than non-anodized piston domes. Manufactured by Namura and identified by manufacturer and vendor part number NX-20013-BK, this top-end kit is a practical replacement solution for maintaining proper engine operation and restoring performance on compatible Kawasaki KX85 motorcycles. Confirm model year and application before installation.
