Restore reliable top-end performance with the Namura NA-20005K Standard Bore Top End Kit, designed for select Kawasaki KVF300 Brute Force and Arctic Cat 300 DVX models. This 11:1 compression kit includes the essential components needed for a complete top-end rebuild, including a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit. The standard-bore configuration is designed for compatible original-cylinder applications.
The piston uses a hypereutectic casting process that increases silicon content to help control expansion, improve wear resistance, and withstand elevated cylinder temperatures. Its MOS2, or Teflon/molybdenum, coated skirts use a rolled-on application process for a durable bond that helps reduce friction, improve heat transfer, and minimize the risk of cold seizures. Machined smooth heads help reflect combustion heat and reduce carbon buildup, while anodized domes improve heat resistance and piston durability.
Fitment includes 2013–2017 Kawasaki KVF300 Brute Force models with SRA and 2009–2014 Arctic Cat 300 DVX models as listed. Verify the vehicle year, model, cylinder configuration, and standard-bore requirements before installation. Manufactured by Namura and identified by manufacturer part number NA-20005K, this kit is suited for replacing worn or damaged top-end components during engine service.
