Restore top-end performance with the NAMURA NA-20000-2K Top End Kit for Kawasaki KLF300B Bayou 2x4 models. This 76.45 mm (+0.50 mm) kit features an 11:1 compression ratio and is designed for 1988–1997 Kawasaki KLF300B Bayou 2x4 [SRA] applications. The complete kit includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit for a convenient and comprehensive engine rebuild.
The NAMURA piston uses a hypereutectic casting process with increased silicon content to help reduce expansion, improve wear resistance, and withstand elevated cylinder temperatures. MOS2, or Teflon/Molybdenum, coated skirts are applied using a rolled-on process that creates a durable bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. Machined smooth heads help reflect combustion heat and reduce carbon buildup, supporting piston protection and consistent engine operation.
Anodized domes add heat resistance and durability, making this piston well suited for demanding recreational and utility ATV use. Designed as a replacement top-end solution, the NAMURA NA-20000-2K helps refresh compression and reliability when installed with properly prepared cylinder components and according to the engine manufacturer’s service procedures. Verify the model, year, overbore requirement, and cylinder condition before installation.
