The NAMURA NX-30000-2K Top End Kit is designed for select 1989-2000 Suzuki RM125 two-stroke applications and includes the essential components needed to refresh the top end of the engine. This kit includes a piston, piston rings, wrist pin, retaining clips, top end bearing, and gasket kit for a complete replacement solution. The 54.5 mm piston size is intended for compatible SCEM composite cylinder applications and is engineered to support reliable fitment and performance.
Feature: MOS2 (Teflon/Molybdenum) coated piston skirts use a rolled-on application process that creates a bond significantly stronger than many spray-on coatings. The coating promotes heat transfer, reduces friction, and helps reduce the risk of cold seizures. The machined smooth piston head reflects combustion heat and helps limit carbon buildup, protecting the piston crown during operation.
Feature: Anodized piston domes improve heat resistance and durability, while the hypereutectic casting process increases silicon content for controlled expansion, added wear resistance, and improved tolerance of elevated cylinder temperatures. These design elements help provide dependable service in demanding motocross and off-road riding conditions.
Fitment includes 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, and 2000 Suzuki RM125 models. Verify the model year, cylinder specification, and required piston size before installation. Manufacturer part number: NX-30000-2K. Vendor part number: 185-30002.
