Cylinder Works 09-12 Honda CRF 450 R 450cc Standard Bore Cylinder Kit 12.0:1 Comp. 96mm

This kit from Cylinder Works gives you everything you need to get your 2009-2012 Honda CRF 450 R back to its original performance level. Inside this box, you'll find a cast aluminum Cylinder Works cylinder, a Vertex piston, and all the necessary gaskets to complete the job. It’s a complete package designed to restore lost horsepower and bring your engine back to life.

The cylinder itself is built with a 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. That lower friction translates to better efficiency and extreme durability for the cylinder wall. To ensure your piston rings seal properly and the cylinder retains oil effectively, the bore is precision diamond honed to exact dimensions and the right surface finish. This attention to detail is key for getting the most out of your engine rebuild.

This kit is a solid option for anyone looking to replace a worn-out cylinder or rebuild their engine. It offers a competitive price point compared to OEM parts while delivering the performance you expect. Make sure to refer to the manufacturer's installation instructions for specific details on assembly and break-in procedures.
