Cylinder Works 04-07 Honda CRF 250 R 250cc Standard Bore Cylinder Kit

This is the Cylinder Works standard bore cylinder kit for your 2004-2007 Honda CRF 250 R. If you're looking to bring your engine back to life after wear and tear, this kit is designed to restore lost horsepower and performance. It's a complete package that includes everything you need to get your 250cc engine running strong again, offering a solid alternative to expensive OEM parts.

Inside this kit, you'll find a cast aluminum cylinder from Cylinder Works, known for its well-built construction. It also comes with a Vertex Piston, a respected name in performance engine components, ensuring you get reliable parts for your rebuild. 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. That tighter tolerance and the extreme durability of the NSC plating help ensure a long service life for your engine. Plus, the bore is precision diamond honed to exact dimensions and the right surface finish. This critical step ensures your piston rings seal properly against the cylinder wall, which is key for both power output and keeping oil where it belongs.

When you're rebuilding the top end of your CRF 250 R, having a complete kit like this simplifies the process. It includes the cylinder, piston, and all the necessary gaskets to get the job done. This means you can focus on the rebuild itself, knowing you have the core components ready to go. It's a well-put-together package aimed at getting your bike back on the trail with renewed power.
