Cylinder Works 01-13 Yamaha WR 250 F 250cc Standard Bore High Compression Cylinder Kit 13.5:1 Comp.

If you're looking to rebuild the top end of your 2001-2013 Yamaha WR 250 F and want to get more power out of it, this high compression cylinder kit from Cylinder Works is a solid option. This kit is designed to bring your engine back to life, giving you that lost horsepower and performance that makes riding enjoyable.

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 up and down. It also contributes to extreme durability, so this cylinder should last you a long time. The bore is precision diamond honed to exact dimensions and has the right surface finish to ensure your piston rings seal properly and retain oil, which is crucial for engine health and performance.

With a 13.5:1 compression ratio, this kit is built for riders who want a noticeable bump in power. It's a great way to get more out of your WR 250 F compared to just replacing parts with standard OEM options, often at a competitive price point.
