Cylinder Works 13-16 Honda CRF 450 R 450cc Standard Bore Cylinder Kit 12.5:1 Comp. 96mm

The nickel silicon carbide (NSC) electroplate bore on this Cylinder Works cylinder kit is a notable detail, allowing for tighter tolerances and reduced friction. This advanced plating method contributes to extreme durability, which is crucial for maintaining performance over time. This kit is designed to bring your 2013-2016 Honda CRF 450 R back to its original horsepower and overall performance levels, offering a competitive alternative to OEM replacements.

Included in this kit is a cast aluminum cylinder from Cylinder Works, a Vertex piston, and all the necessary gaskets to complete the installation. The cylinder bore is precision diamond honed to exact dimensions, ensuring a proper surface finish that promotes good ring seal and effective oil retention. This attention to detail in the bore finish is key to preventing oil blow-by and ensuring the piston operates smoothly within the cylinder.

When rebuilding the top end of your CRF 450 R, a standard bore cylinder kit like this one is a solid option for restoring lost power. It's important to ensure all components are clean and properly lubricated before installation, and to follow the manufacturer's recommended torque specifications for all fasteners to achieve the best results and ensure the longevity of the engine.
