Cylinder Works 19-20 Honda CRF 450 R 450cc Standard Bore High Compression Cylinder Kit 14.4:1 Comp.

This is the Cylinder Works 10010-K02HC high compression cylinder kit for the 2019-2020 Honda CRF 450 R. If you're looking to get your CRF 450 R's engine back to peak performance, this kit is designed to restore lost horsepower and torque. It's a standard bore kit, meaning it matches the original cylinder dimensions, making installation more straightforward.

What sets this kit apart is the 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. This not only helps with performance but also contributes to the cylinder's extreme durability. The bore is also precision diamond honed to exact dimensions, creating the perfect surface finish. This is crucial for ensuring the piston rings seal properly against the cylinder wall, which is key for good compression and efficient oil retention.

Included in this kit is a cast aluminum Cylinder Works cylinder, a Vertex piston, and all the necessary gaskets to complete the job. When compared to buying individual OEM parts, this kit offers a competitive price point for restoring your engine's power. Make sure to refer to the manufacturer's installation instructions for specific details on assembly and break-in procedures.
