Cylinder Works 16-17 Honda CRF 250 R 250cc Standard Bore Cylinder Kit 13.5:1 Comp. 76.8mm

If you're rebuilding the top end of your 2016-2017 Honda CRF 250 R, this Cylinder Works standard bore cylinder kit is a solid option to get your engine running like new again. This kit is designed to restore lost horsepower and performance, giving you that crisp throttle response you're looking for. It's a complete package, including the Cylinder Works cast aluminum cylinder, a Vertex piston, and all the necessary gaskets to get the job done right.

What sets this kit apart is the attention to detail in the cylinder's construction. It features a nickel silicon carbide (NSC) electroplate bore. This advanced plating allows for tighter tolerances, which means less friction as the piston moves up and down. That lower friction translates to better efficiency and extreme durability over time. Plus, the bore is precision diamond honed to exact dimensions and the right surface finish. This ensures your piston rings seal properly against the cylinder wall, which is crucial for good compression and proper oil retention, keeping your engine well-lubricated.

This kit offers an OEM-style replacement that brings your engine back to its original specifications, but with some well-made enhancements for longevity. It's a comprehensive solution for anyone looking to bring their CRF 250 R's engine back to peak condition without the high cost of some OEM parts.
