Athena 10-13 Yamaha YZ 450 F 96.97mm 4T Forged Racing Piston

This is the Athena 4-stroke forged racing piston, specifically made for the 2010-2013 Yamaha YZ 450 F. It measures 96.97mm, which is a common size for engine rebuilds on this model. A well-built piston is crucial for getting your engine running strong again, especially if you're looking for better performance than the original part.

Athena makes these pistons using a reverse extrusion process and then machines them with CNC tools to very tight tolerances, less than 0.01 mm. They're crafted from special alloys that include nickel, silica, and aluminum. This construction aims to give you the same reliability as your original piston but with added resistance and better performance. The smooth surface of the piston helps with consistent fuel flow and proper combustion.

This piston is a solid option if you're rebuilding the top end of your Yamaha YZ 450 F and want a part that's built to last and perform. Keep in mind that this part is not CARB approved and cannot be shipped to California.
