Cylinder Works 04-05 Honda TRX 450 R 450cc +3mm Big Bore Cylinder Kit 479cc 10.5:1 Comp. 97mm

If you're looking to get more power out of your 2004-2005 Honda TRX 450 R, this big bore cylinder kit from Cylinder Works is a solid option. It takes your stock 450cc engine and bumps it up to a 479cc displacement, giving you a noticeable increase in horsepower and overall engine performance. This kit is designed to look like the original cylinder but perform like a race-ready component.

The kit includes a hand-matched Vertex piston, which is crucial for proper fit and function within the larger bore cylinder. You also get a complete top-end gasket kit with O-rings, so you have everything you need to get the job done. The cylinder itself is made from a 2618 aluminum alloy, which is known for being strong and durable, able to handle the increased demands of a bigger displacement engine. This material choice helps ensure the longevity of the kit even under hard use.

This is a comprehensive kit designed to simplify the process of upgrading your TRX 450 R's engine. By providing the cylinder, piston, and all necessary gaskets in one package, it saves you the hassle of sourcing individual OEM parts. The 10.5:1 compression ratio is a good balance for improved power without requiring extreme fuel octane, making it a practical choice for many riders.
