Cylinder Works 10-13 Yamaha YZ 450 F 450cc Standard Bore High Compression Cylinder Kit 13.5:1 Comp.

The nickel silicon carbide (NSC) electroplate bore on this Cylinder Works cylinder is a notable detail, allowing for tighter tolerances and reduced friction. This means the cylinder can operate more efficiently and last longer. This kit is built to bring your 2010-2013 Yamaha YZ 450 F back to its peak performance, offering a 13.5:1 compression ratio for a noticeable boost in power.

Inside this kit, you'll find a cast aluminum Cylinder Works cylinder, a Vertex piston, and all the necessary gaskets to get your engine rebuilt. The NSC bore is 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 immediate performance and long-term durability, helping you get back on the track with confidence.

Compared to the cost of OEM replacements, this Cylinder Works kit offers a competitive price point for restoring lost horsepower and overall engine performance. It’s a solid option for riders looking to refresh their YZ 450 F's engine with well-built components that are designed for durability and improved output.
