Cylinder Works 19-20 Honda CRF 450 R 450cc Standard Bore Cylinder Kit 13.5:1 Comp. 96mm

This is a Cylinder Works standard bore cylinder kit for the 2019-2020 Honda CRF 450 R. It's designed to bring your 450cc engine back to its original horsepower and performance levels. If you're looking to rebuild the top end of your CRF 450 R, this kit gives you everything you need to get the job done right.

The kit includes a cast aluminum cylinder from Cylinder Works, a Vertex piston, and all the necessary gaskets to complete the installation. What really sets this cylinder apart is its bore technology. It features a nickel silicon carbide (NSC) electroplate bore. This advanced plating allows for very tight tolerances, which means less friction as the piston moves. It also contributes to extreme durability, helping your engine last longer. The bore is precision diamond honed to exact dimensions and has a specific surface finish. This ensures your piston rings seal properly against the cylinder wall, which is crucial for both compression and retaining oil where it needs to be.

With a 13.5:1 compression ratio and a 96mm bore, this kit is a solid option for restoring your Honda CRF 450 R's engine. It offers a competitive price point compared to OEM replacements while providing well-built components designed for performance and longevity.
