Cylinder Works 04-05 Honda TRX 450 R 450cc Standard Bore High Compression Cylinder Kit 13.1:1 Comp.

This kit from Cylinder Works gives you everything you need to get your 2004-2005 Honda TRX 450 R back to peak performance. 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 designed to restore the horsepower and performance your ATV had when it was new, offering a solid alternative to OEM parts at a competitive price.

The cylinder itself is built with a nickel silicon carbide (NSC) electroplate bore. This advanced plating technique allows for very tight tolerances, which means less friction as the piston moves up and down. That lower friction translates to better efficiency and durability over time. Plus, the bore is precision diamond honed to exact dimensions and given a specific surface finish. This careful honing is crucial for ensuring the piston rings seal properly against the cylinder wall, which is key for good compression and keeping oil where it belongs, preventing it from getting into the combustion chamber.

With a 13.1:1 compression ratio, this kit is built for riders looking for improved power output. It's a well-built package that addresses the core components needed for a cylinder replacement or an upgrade. Make sure to refer to the manufacturer's installation instructions for specific details on the rebuild process.
