Namura NX-20014K Top End Kit for 2014–2020 Kawasaki KX100, 52.44 mm Standard Bore

Restore reliable top-end performance with the Namura NX-20014K Top End Kit for Kawasaki KX100 models. Designed for standard-bore applications with a 52.44 mm piston size, this kit is intended for motorcycles equipped with Nikasil-plated cylinders. It provides the key components needed for a professional top-end rebuild, helping support dependable engine operation and consistent performance.

The kit includes a piston, piston rings, wrist pin, wrist-pin clips, top-end bearing, and gasket kit. The hypereutectic casting process adds silicon for reduced expansion, increased wear resistance, and improved durability under elevated cylinder temperatures. The piston also features a machined smooth head to reflect combustion heat and help reduce carbon buildup, supporting protection of the piston crown during operation.

Additional performance-focused construction includes an anodized dome for increased heat resistance and durability, along with MOS2 Teflon/molybdenum-coated skirts. The rolled-on coating process creates a strong bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. The Namura NX-20014K is a direct fit for 2014, 2015, 2016, 2017, 2018, 2019, and 2020 Kawasaki KX100 motorcycles. Verify cylinder condition, bore specification, and application details before installation.
