Athena 20-22 Yamaha YZ 450F 97mm Bore 450cc Stock Bore Complete Cylinder Kit

Athena is a well-known name in high-performance engine components, and this complete cylinder kit for your 2020-2022 Yamaha YZ 450F is a prime example of their commitment to quality. Designed to match the original spare parts' performance, this kit ensures your bike runs reliably and smoothly, just like it did when it was new. If you're looking to restore your engine's power or replace worn-out components, this kit offers a solid solution.

What makes this kit stand out is its construction. The aluminum cylinder is lightweight, which helps with overall bike handling and engine responsiveness. It features a nickel-silicon coating on the barrel, a tough surface that holds up well to the demands of regular riding and helps manage heat. The included piston is specifically designed to reduce friction, meaning more of your engine's power gets to the rear wheel and less is lost to internal drag. This attention to detail in materials and design is what Athena is known for.

When you open the box, you'll find everything you need to get your engine back in top shape. The kit comes complete with the standard bore aluminum cylinder, a full piston assembly including the piston pin and rings, and all the necessary gaskets to ensure a proper seal. This makes the installation process more straightforward, as you won't have to hunt for individual parts. Just remember that this kit is not CARB approved, so it cannot be shipped to California.
