Athena 10-13 Honda CRF 250 R Stock Bore Complete Cylinder Kit

This is the Athena Complete Cylinder Kit for your 2010-2013 Honda CRF 250 R. If you're rebuilding the top end of your engine, this kit aims to bring it back to its original performance and reliability. It's designed to match the factory specifications, ensuring a smooth running engine.

The cylinder itself is made from lightweight aluminum, which helps with heat dissipation. It features a nickel-silicon coating on the barrel, a tough surface that's known for its durability and low friction. The included piston is also designed to further reduce friction, which means less power loss and potentially longer life. This kit comes with everything you need to get the job done: the standard bore aluminum cylinder, a complete piston assembly with pin and rings, and all the necessary gaskets to seal everything up properly.

When you're putting this kit in, make sure to follow the manufacturer's installation instructions closely, especially regarding break-in procedures. This will help ensure the new components seat correctly and perform as intended for the long haul.
