Cylinder Works 20-23 Yamaha WR 250 F 250cc Standard Bore High Compression Cylinder Kit 14.7:1 Comp.

If you're looking to rebuild the top end of your 2020-2023 Yamaha WR 250 F and want to get more power out of your engine, this Cylinder Works High Compression Cylinder Kit is a solid option. This kit is designed to bring your 250cc engine back to life with improved performance compared to a stock setup.

This kit includes a cast aluminum cylinder from Cylinder Works, a Vertex piston, and all the necessary gaskets to get the job done. The cylinder itself features a nickel silicon carbide (NSC) electroplate bore. This advanced plating allows for very tight tolerances, which means less friction as the piston moves and significantly improved durability. It's also precision diamond honed to exact dimensions, ensuring your piston rings seal properly and the cylinder walls hold oil effectively for better lubrication and longevity.

With a 14.7:1 compression ratio, this kit is built for riders who want a noticeable boost in power and responsiveness. It's a complete package designed to restore your WR 250 F's horsepower and performance, offering a competitive alternative to OEM replacement parts.
