The Namura NX-30000K Top End Kit is a complete replacement solution for select Suzuki RM125 two-stroke models. Designed for a standard-bore application with a 53.94 mm piston, this kit includes the essential components needed to refresh the top end and restore reliable engine performance. The kit contains a piston, piston rings, wrist pin, wrist-pin clips, top-end bearing, and gasket kit.
The piston features MOS2, or Teflon and molybdenum, coated skirts applied through a rolled-on process for a durable bond. This coating 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 durability. Namura's hypereutectic casting process adds silicon for controlled expansion, increased wear resistance, and improved durability under elevated cylinder temperatures.
This Namura top-end kit fits 1989-2000 Suzuki RM125 models, including model years 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, and 2000. Verify the motorcycle model year and cylinder configuration before installation. Manufacturer part number: NX-30000K. Vendor part number: 185-3000.
