Restore top-end performance with the NAMURA NA-30080K Standard Bore Top End Kit, designed for select Kawasaki KFX 80 and Suzuki LT80 Quadsport models. This complete kit includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit for a convenient engine rebuild. The piston features a 49.96 mm standard-bore size and an 11:1 compression ratio for reliable fitment and dependable performance.
Engineered for durability, the NAMURA piston uses a hypereutectic casting process that increases silicon content to help control expansion, improve wear resistance, and withstand elevated cylinder temperatures. The MOS2 Teflon/molybdenum-coated skirts are applied through a rolled-on process that creates a stronger bond than conventional spray-on coatings. This coating helps improve heat transfer, reduce friction, and minimize the risk of cold seizures during operation.
The machined smooth head reflects combustion heat and helps reduce carbon buildup, supporting piston protection and efficient engine operation. An anodized dome adds heat resistance and durability, while providing greater strength than a non-anodized piston dome. The kit is suitable for 2003–2006 Kawasaki KFX 80 models and 1989–1994 Suzuki LT80 Quadsport models. Verify the model year, engine configuration, and standard-bore requirement before installation.
