The Namura NX-30080-6K Top End Kit is a performance replacement kit designed for 1991–2000 Suzuki RM80 models. This 48.93 mm, 11:1 compression kit provides the essential components needed to refresh the top end of the engine, including a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit. It is engineered for reliable fitment and dependable service in compatible Suzuki RM80 applications.
The piston uses Namura’s hypereutectic casting process, which increases silicon content to help control 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 strong bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. The machined smooth head helps reflect combustion heat and reduce carbon buildup, supporting piston protection and consistent engine performance.
The anodized dome improves heat resistance and durability, providing increased protection under demanding operating conditions. This top-end assembly is intended for riders and technicians seeking a complete replacement solution for compatible Suzuki RM80 engines. Verify the bore size, compression ratio, and engine specifications before installation to ensure proper application. The manufacturer part number is NX-30080-6K, and the vendor part number is 185-30806.
