Athena 08-13 Yamaha YZ 250 F Complete Stock Bore Cylinder Kit

The barrel on this Athena cylinder kit features a nickel-silicon coating, a tough material chosen for its durability and ability to work well with the piston. This kit is built to match the original performance of your 2008-2013 Yamaha YZ 250 F, offering reliable operation and smooth running. It’s a complete package designed to get your engine back to factory specifications.

You're getting a well-built aluminum cylinder with a standard bore, meaning it's designed to fit your engine without modifications. Inside, you'll find a piston engineered to reduce friction, which helps with efficiency and longevity. This attention to detail means you can expect consistent performance from your bike. The kit comes with everything you need to get the job done: the cylinder, a complete piston assembly (including the piston pin and rings), and all the necessary gaskets for a proper seal.

When you're rebuilding the top end of your YZ 250 F, having a complete kit like this from Athena simplifies the process. It ensures all the critical components are designed to work together seamlessly. Just remember that this kit is not CARB approved and cannot be shipped to California.
