Upgrade the top end of your 2001–2003 Suzuki RM125 with the Namura NX-30004K Top End Kit. Designed for standard-bore applications, this kit includes the essential components needed for a reliable piston replacement and top-end rebuild, including a piston, piston rings, wrist pin, wrist-pin clips, top-end bearing, and gasket kit. It is engineered for fitment with Suzuki RM125 models using the original 53.94 mm standard bore.
The Namura NX-30004K piston uses a hypereutectic casting process that increases silicon content to help reduce expansion, improve wear resistance, and withstand elevated cylinder temperatures. Its MOS2 coating, formulated with Teflon and molybdenum, is applied using a rolled-on process designed to provide a durable bond while reducing friction, improving heat transfer, and helping minimize the risk of cold seizures. These features support dependable performance in demanding two-stroke riding conditions.
A machined-smooth piston head helps reflect combustion heat and reduce carbon buildup, while the anodized dome improves heat resistance and durability. The included components provide a practical solution for restoring compression and refreshing the top end during routine maintenance or engine repair. The kit is manufactured by Namura and supplied under vendor part number NX-30004K; manufacturer part number information is not separately specified for this product.
