Athena 10-17 Yamaha YZ 450 F 97mm 450cc Standard Bore Cylinder Kit w/Gaskets (Excl Piston)

This Athena cylinder kit is a direct replacement for your 2010-2017 Yamaha YZ 450 F, bringing it back to its original performance and reliability. It features a standard bore, measuring 97mm, for a 450cc displacement, ensuring it matches the factory specifications. The kit is built with a lightweight aluminum cylinder that incorporates a nickel-silicon barrel coating, which helps reduce friction and improve durability. This construction contributes to the optimal smoothness and extreme reliability you expect from your machine.

Athena has developed this kit to ensure it performs just like the original spare parts. The design focuses on reducing friction, which is key for maintaining engine health and performance over time. While this kit includes the cylinder and all necessary gaskets, please note that the piston is sold separately. This allows you the flexibility to choose a specific piston if needed, or to replace just the cylinder and gaskets if your existing piston is still in good condition.
