Athena 03-06 Yamaha WR 450 F 95mm 450cc Standard Bore Cylinder Kit w/Gaskets (Excl Piston)

This Athena cylinder kit uses a lightweight aluminum cylinder with a nickel-silicon barrel coating, a design choice that helps manage heat and wear. It's built to match the original performance and reliability of your 2003-2006 Yamaha WR 450 F, ensuring your engine runs smoothly.

The nickel-silicon coating on the barrel is a notable feature that contributes to its durability and the piston's ability to reduce friction. This kit is designed to be a direct replacement, bringing your engine back to its factory specifications. It's a well-built component for riders who want to restore their machine to its peak operating condition.

This kit comes with the aluminum cylinder and all the necessary gaskets to complete the installation. Remember to check your service manual for specific installation procedures and any additional parts you might need for your rebuild.
