The Namura NA-20065-2K Top End Kit is designed for Kawasaki KVF650 ATV applications and includes the essential components needed for a reliable top-end rebuild. This 80.46 mm oversize kit features an 11:1 compression piston, piston rings, wrist pin, retaining clips, top-end bearing, and a complete gasket kit. It is engineered to support proper fitment and dependable performance when servicing a compatible cylinder.
Features: MOS2 (Teflon/Molybdenum) coated skirts use a rolled-on application process that creates a bond reported to be 10 times stronger than many spray-on coatings. The coating helps improve heat transfer, reduce friction, and minimize the risk of cold seizures. Machined smooth piston heads reflect combustion heat and help reduce carbon buildup, protecting the piston crown while supporting consistent engine operation.
The piston also includes an anodized dome for increased heat resistance and durability. According to manufacturer testing, anodized domes can be 75% stronger than non-anodized designs. Namura's hypereutectic casting process increases silicon content to help reduce expansion, improve wear resistance, and withstand elevated cylinder temperatures. These features make the kit suitable for riders and technicians seeking a durable replacement for worn or damaged top-end components.
Fitment includes 2005–2011 and 2013 Kawasaki KVF650 Brute Force 4X4 models with SRA, plus 2002 and 2003 Kawasaki KVF650 Prairie 4X4 models with SRA. Verify the model year, cylinder specification, and required oversize before installation. Manufacturer: Namura. Vendor part number: NA-20065-2K.
