Cylinder Works 02-06 Honda CRF 450 R 450cc Standard Bore High Compression Cylinder Kit 12.5:1 Comp.

If you're rebuilding the top end of your 2002-2006 Honda CRF 450 R and looking to get more power out of your engine, this Cylinder Works High Compression Cylinder Kit is a solid option. This kit is designed to restore lost horsepower and performance, giving your CRF 450 R a new lease on life. It features a standard bore size, meaning it's a direct replacement for your original cylinder, making installation more straightforward.

The heart of this kit is the cast aluminum cylinder itself, which is treated with a nickel silicon carbide (NSC) electroplate bore. This advanced plating technique allows for tighter tolerances, which translates to lower friction between the piston and cylinder wall. This not only helps your engine run more efficiently but also contributes to extreme durability, meaning this cylinder can handle the demands of aggressive riding. The bore is also precision diamond honed to exact dimensions, ensuring a proper surface finish for excellent ring seal and oil retention, which are critical for engine health and performance.

Included in this kit is a Vertex piston and all the necessary gaskets to complete the installation. This comprehensive package means you won't have to hunt for individual parts, making the rebuild process smoother. The high compression ratio of 12.5:1 is designed to give your CRF 450 R a noticeable boost in power and throttle response, especially when paired with appropriate fuel and tuning.
