Athena 10-18 Yamaha YFZ 450 Bill Balance Edition 95mm 450cc Standard Bore Cylinder Kit

The nickel-silicon coating on the barrel of this Athena cylinder kit is a key detail that helps with durability and performance. This coating, combined with a lightweight aluminum cylinder and a piston designed to reduce friction, means you're getting a well-built component that aims to match the original equipment's reliability and smooth operation. It's designed for the Yamaha YFZ 450 Bill Balance Edition models from 2010 to 2018, using a standard 95mm bore for a 450cc displacement.

When you're rebuilding the top end of your YFZ 450, a cylinder kit like this one from Athena is a critical piece. They've focused on materials and design to ensure it performs as expected. The aluminum cylinder is chosen for its light weight, which is always a plus on an ATV, and the piston's specific design helps keep things running smoothly, reducing wear over time. This attention to detail is what you'd expect from a component intended for reliable operation.

This kit comes with everything you need to get the cylinder installed: the aluminum cylinder itself, a complete piston assembly including the pin and rings, and all the necessary gaskets to seal everything up properly. Just remember that this kit is not CARB approved, so it cannot be shipped to California. Always refer to the manufacturer's installation instructions for the correct procedures and any specific tool requirements.
