Cylinder Works 21-23 Honda CRF 450 R 450cc Standard Bore High Compression Cylinder Kit

Cylinder Works is known for making solid engine components that help racers and everyday riders get the most out of their machines. This high compression cylinder kit is a prime example, designed to bring your 2021-2023 Honda CRF 450 R back to its peak performance. If you're looking to restore lost horsepower or even gain a bit more grunt out of your 450cc engine, this kit is built to do just that.

What sets this kit apart is the attention to detail in its construction. You get a cast aluminum cylinder from Cylinder Works, paired with a Vertex piston. The bore itself features a nickel silicon carbide (NSC) electroplate. 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 you can count on this cylinder to hold up under demanding use. The bore is then precision diamond honed to exact dimensions. This critical step ensures a proper surface finish for the piston rings to seal against, which is key for both power and oil retention. This means you'll get a better seal, less blow-by, and your engine will hold oil effectively.

This kit includes the cylinder, a Vertex piston, and all the necessary gaskets to get the job done. It's a complete package designed to be a direct replacement for your stock cylinder, offering a way to restore your CRF 450 R's horsepower and performance at a competitive price compared to OEM options. When you're rebuilding your top end, having a well-made cylinder kit like this makes a significant difference in the final outcome.
