Cylinder Works 2017 Yamaha YFZ 450 450cc Standard Bore High Compression Cylinder Kit

This kit from Cylinder Works gives you everything you need to rebuild the top end of your 2017 Yamaha YFZ 450 with a high compression setup. Inside, you'll find a cast aluminum Cylinder Works cylinder, a Vertex piston, and all the necessary gaskets to get your engine back to peak performance. It's a solid way to restore lost horsepower and get your ATV running strong again, often at a better price than going with OEM parts.

The cylinder itself is built with a nickel silicon carbide (NSC) electroplate bore. This advanced plating allows for very tight tolerances, which means less friction as the piston moves up and down. That lower friction helps with efficiency and durability. Plus, this bore is precision diamond honed to exact dimensions, creating the perfect surface finish. This is crucial for ensuring the piston rings seal properly against the cylinder wall, which is key for good compression and keeping oil where it belongs.

If you're looking to get more out of your YFZ 450's engine, this high compression cylinder kit is a well-built option. It's designed to bring your engine back to life and give it a bit more punch.
