Athena 10-18 Yamaha YFZ 450 Bill Balance Edition 94.95mm 4T Forged Racing Piston

Forged from a special aluminum alloy with nickel and silica, this Athena piston is built for demanding performance on your 10-18 Yamaha YFZ 450 Bill Balance Edition. The forging process creates a stronger, more durable piston than cast alternatives, and Athena uses advanced CNC machining to hold tolerances to less than 0.01 mm, ensuring a precise fit and optimal performance. This means you get the reliability you expect from an OE part, but with added resistance and improved performance for racing applications.

The smooth profile of this piston helps ensure regular airflow and proper flame propagation within the cylinder, contributing to efficient combustion. Athena has been making motorcycle parts for over 40 years, and their experience shows in the well-built nature of this racing piston. It's designed to handle the stresses of off-road riding while giving you that extra edge.
