Cylinder Works 16-18 Yamaha WR 450 F 450cc Standard Bore High Compression Cylinder Kit 13.5:1 Comp.

Cylinder Works is known for providing well-built engine components that offer a solid value, and this high compression cylinder kit for your 2016-2018 Yamaha WR 450 F is no exception. If you're looking to restore or even improve the horsepower and performance of your off-road machine, this kit is designed to get the job done. It's a standard bore kit, meaning it uses the original piston size, making installation more straightforward.

What sets this kit apart is the attention to detail in its construction. The cylinder itself is cast aluminum, a common and effective material for these applications. Inside, you'll find a Nickel Silicon Carbide (NSC) electroplate bore. This advanced plating allows for very tight tolerances, which translates to lower friction as the piston moves. That lower friction means less power loss and improved durability over time. The bore is also precision diamond honed to exact dimensions, ensuring the piston rings seal properly against the cylinder wall. This proper seal is crucial for both maintaining compression and retaining oil, which keeps the cylinder walls lubricated and reduces wear.

This kit comes with everything you need to get your engine back to peak performance: the Cylinder Works cylinder, a Vertex piston, and all the necessary gaskets. The high compression ratio of 13.5:1 is designed to give you a noticeable boost in power and throttle response compared to stock, making your WR 450 F feel more potent on the trail or track. When you're rebuilding the top end of your engine, using a kit like this ensures all the critical components are designed to work together seamlessly.
