Restore reliable top-end performance with the Namura NX-20060-CK Top End Kit, designed for select 1985–1994 Kawasaki KX60 two-stroke motorcycles with a Nikasil-plated cylinder. This complete kit includes the piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit needed for a professional top-end rebuild. The precision-engineered components are designed to support proper fitment, dependable compression, and long-lasting service in demanding riding conditions.
The piston features Namura’s MOS2, or Teflon/Molybdenum, coated skirts. This rolled-on coating process creates a strong bonded surface that helps reduce friction, improve heat transfer, and minimize the risk of cold seizures. The machined smooth head reflects combustion heat and helps limit carbon buildup, supporting piston protection and consistent engine operation. An anodized dome adds heat resistance and durability, while the hypereutectic casting process provides increased silicon content for controlled expansion, enhanced wear resistance, and improved performance at elevated cylinder temperatures.
This Namura top-end kit is intended for Kawasaki KX60 models from 1985 through 1994 and is designed for a 42.97 mm piston size with a 0.02 mm oversize specification. Confirm the motorcycle year, model, cylinder condition, and required piston clearance before installation, particularly when servicing a Nikasil-coated cylinder. The manufacturer part number is NX-20060-CK, and the vendor part number is 185-2060C.
