Cylinder Works 04-05 Honda TRX 450 R 450cc Standard Bore Cylinder Kit 10.5:1 Comp. 94mm

If you're rebuilding the top end of your 2004 or 2005 Honda TRX 450 R, this standard bore cylinder kit from Cylinder Works is a solid option to get your ATV running strong again. This kit is designed to replace your original cylinder, bringing back lost horsepower and performance without needing to bore out your existing cylinder. It's a complete package, including the cylinder, a Vertex piston, and all the necessary gaskets to get the job done right.

What sets this kit apart is the cylinder itself. It's constructed from cast aluminum and features a nickel silicon carbide (NSC) electroplate bore. This advanced plating allows for very tight tolerances, which means less friction and improved durability. The bore is also precision diamond honed to exact dimensions, ensuring your piston rings seal properly and retain oil effectively. This attention to detail in the bore finish is crucial for both performance and longevity, helping to prevent blow-by and oil consumption.

This kit comes with a 10.5:1 compression ratio and a 94mm standard bore, making it a direct replacement for stock specifications. It's a well-built component that aims to provide a competitive price point compared to OEM options, giving you a reliable way to restore your TRX 450 R's engine.
