Cylinder Works 04-06 Honda CRF 450 R 450cc Standard Bore Cylinder Kit 12.1:1 Comp. 96mm

If you're rebuilding the top end of your 2004-2006 Honda CRF 450 R, this standard bore cylinder kit from Cylinder Works is a solid option to get your engine running like new again. This kit is designed to restore lost horsepower and performance, offering a competitive alternative to OEM parts. It includes a cast aluminum cylinder, a Vertex piston, and all the necessary gaskets to complete the job.

What sets this kit apart is the cylinder's bore treatment. It features a nickel silicon carbide (NSC) electroplate, which is a tough coating that allows for very precise tolerances. This means less friction as the piston moves, leading to improved durability and better performance over time. The bore is also diamond honed to exact dimensions, ensuring a perfect surface finish. This precise finish is crucial for proper piston ring seal and for retaining oil, which keeps the cylinder walls lubricated and reduces wear.

This kit is a complete package for a standard bore rebuild, meaning it's designed to fit without needing to machine the original cylinder. You'll get a well-built cylinder and a quality piston from Vertex, along with the gaskets needed to put it all back together. It's a straightforward way to bring your CRF 450 R's engine back to its full potential.
