Athena 18-19 Honda CRF 250 R Stock Bore Complete Cylinder Kit

This Athena cylinder kit is built with a lightweight aluminum cylinder featuring a nickel-silicon coating on the barrel. This coating helps reduce friction, working together with a specially designed piston to ensure smooth operation and maintain the same performance you'd expect from your original Honda CRF 250 R's engine. It’s a well-built replacement designed for reliability.

When you're looking to get your 2018 or 2019 Honda CRF 250 R back to its factory performance, a complete cylinder kit like this one from Athena is a solid choice. It comes with everything you need to rebuild that section of your engine: the standard bore aluminum cylinder, a complete piston assembly including the piston pin and rings, and all the necessary gaskets to seal everything up properly. The focus here is on restoring that original smoothness and dependability.

It's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for the correct procedures and any specific torque requirements when installing this kit on your motorcycle.
