The Namura NX-20060-BK Top End Kit is designed for 1985–1994 Kawasaki KX60 models equipped with a Nikasil-plated cylinder. This complete top-end solution includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit for a convenient engine rebuild. The kit is engineered for dependable fitment and performance on the specified Kawasaki KX60 applications.
The piston uses a hypereutectic casting process with increased silicon content to help control expansion, improve wear resistance, and withstand elevated cylinder temperatures. Its MOS2, or Teflon and molybdenum, coated skirts are applied through a rolled-on process that creates a durable bond while reducing friction, improving heat transfer, and helping minimize cold-seizure risk. The smooth-machined head helps reflect combustion heat and reduce carbon buildup, while the anodized dome improves heat resistance and piston durability.
Designed for a 42.96 mm bore with a 0.01 mm oversize specification, the Namura NX-20060-BK kit provides the components needed to restore the top end of compatible Kawasaki KX60 two-stroke engines. Confirm the cylinder condition, bore specification, and model year before installation to ensure proper compatibility. Manufacturer part number: NX-20060-BK. Vendor part number: 185-2060B.
