The Namura NX-30080-2K Top End Kit is designed for reliable engine rebuilding and performance-focused replacement on select Suzuki RM80 models. This complete kit includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit, providing the essential components needed to service the upper end of the engine. The 47.93 mm +0.50 mm piston size is intended for a properly prepared cylinder, while the 11:1 compression ratio supports responsive engine performance.
The piston is manufactured using Namura’s hypereutectic casting process, which increases silicon content to help control expansion, improve wear resistance, and withstand elevated cylinder temperatures. The MOS2 Teflon/molybdenum-coated skirt uses a rolled-on application process for a durable bond that helps reduce friction, improve heat transfer, and minimize the risk of cold seizures. A machined smooth head helps reflect combustion heat and reduce carbon buildup, while the anodized dome improves heat resistance and durability.
This Namura top-end kit fits 1991–2000 Suzuki RM80 motorcycles, including 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, and 2000 models. Confirm cylinder preparation, piston clearance, compression requirements, and model specifications before installation. The manufacturer part number is NX-30080-2K, and the vendor part number is 185-30802.
