Upgrade the top end of your 1988–1997 Yamaha YFS200 Blaster with the NAMURA NA-40002K High-Compression Top End Kit. Designed for standard-bore applications, this complete kit includes a piston, piston rings, wrist pin, wrist-pin clips, top-end bearing, and gasket kit for a convenient engine rebuild solution. The kit features a 65.94 mm piston with an 11:1 compression ratio, providing a dependable replacement for worn or damaged original components.
The NAMURA piston uses MOS2, a Teflon and molybdenum coating applied through a rolled-on process that creates a durable bond. This coating helps improve heat transfer, reduce friction, and minimize the risk of cold seizures. The machined-smooth head reflects combustion heat and helps reduce carbon buildup, supporting piston protection and consistent engine performance.
An anodized dome improves heat resistance and durability, while the hypereutectic casting process increases silicon content to help control expansion and improve wear resistance. These features allow the piston to withstand elevated cylinder temperatures while maintaining reliable operation. The included gasket kit and top-end components help simplify installation when servicing the engine.
Fitment: This NAMURA NA-40002K top end kit fits 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, and 1997 Yamaha YFS200 Blaster models. Verify the standard-bore application and engine configuration before installation.
