Cylinder Works 06-14 Honda TRX 450 ER 450cc STD Bore High Compression Cylinder Kit 13.5:1 Comp.

The nickel silicon carbide (NSC) electroplate bore on this Cylinder Works cylinder kit is a notable detail. This advanced plating allows for tighter tolerances during manufacturing, which translates to lower friction and extreme durability once installed. It’s a well-built component designed to get your Honda TRX 450 ER back to its peak performance.

This kit is built around a standard bore, meaning it's a direct replacement for your original cylinder, simplifying the installation process. It comes complete with a Vertex piston and all the necessary gaskets to get the job done. The high compression ratio of 13.5:1 is specifically chosen to help restore lost horsepower and improve overall performance, giving your ATV a noticeable boost.

The precision diamond honing on the cylinder bore ensures exact dimensions and the proper surface finish. This is critical for ensuring your piston rings seal correctly against the cylinder wall, which is essential for both oil retention and efficient combustion. If you're looking to rebuild the top end of your 2006-2014 Honda TRX 450 ER and want a significant improvement in power, this cylinder kit is a solid option.
