Namura NX-20080-CK2 Top End Kit for 1988–1990 Kawasaki KX80, 47.97 mm Bore

Restore top-end performance on your 1988, 1989, or 1990 Kawasaki KX80 with the Namura NX-20080-CK2 Top End Kit. Designed for applications with a Nikasil cylinder and a 47.97 mm piston size, this kit provides the essential components needed for a complete top-end service. The kit includes a piston, piston rings, wrist pin, wrist-pin clips, top-end bearing, and gasket kit for convenient engine rebuilding.

The Namura NX-20080-CK2 piston is manufactured using a hypereutectic casting process that increases silicon content for controlled expansion, improved wear resistance, and reliable performance at elevated cylinder temperatures. Its MOS2, or Teflon/molybdenum, coated skirt is applied using a rolled-on process that creates a strong bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. A machined smooth head helps reflect combustion heat and resist carbon buildup, supporting consistent operation and piston protection.

An anodized dome adds heat resistance and durability, making the piston well suited for demanding two-stroke service. This Namura top-end kit is designed to fit 1988–1990 Kawasaki KX80 models and is suitable for replacing worn or damaged top-end components during engine maintenance or rebuild work. Verify the existing cylinder, piston specification, and model year before installation to ensure proper compatibility. Manufacturer part number: NX-20080-CK2. Vendor part number: 185-2080C2.
