Restore dependable engine performance with the Namura NX-30080-CK Top End Kit. Designed for select Suzuki RM80 models from 1991 through 2000, this complete top-end replacement kit includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit. The kit is engineered for a 47.45 mm piston size with an 11:1 compression ratio, providing a practical solution for rebuilding the upper portion of the engine.
The piston uses a hypereutectic casting process that increases silicon content to help control expansion, improve wear resistance, and withstand elevated cylinder temperatures. Its MOS2, or Teflon and molybdenum, coated skirts use a rolled-on application process designed to create a stronger bond than conventional spray-on coatings. This coating helps reduce friction, improve heat transfer, and minimize the risk of cold seizures during operation.
Additional piston features support long-term durability and consistent combustion performance. The machined smooth head helps reflect combustion heat and limit carbon buildup, while the anodized dome increases heat resistance and strength compared with non-anodized piston designs. Together, these features help protect the piston under demanding riding conditions while supporting reliable power delivery and engine service life.
The Namura NX-30080-CK fits 1991–2000 Suzuki RM80 motorcycles when matched to the specified engine configuration and piston size. Verify the existing cylinder, bore, and model application before installation. This product is identified by manufacturer part number NX-30080-CK and vendor part number 185-3080C.
