Description

Building on our Ninja 400’s success in the 2020 ASRA Moto3 National Championship, we applied the same race-proven technology to our in-house Ninja 500 with outstanding results. The WORX Airbox, tailored for the 451cc motor, boosts power and torque by 3-5% across the power curve when compared to our Stage 2 setup. The WORX Airbox completely replaces the stock setup, including the stock air filter and velocity stacks, and replaces them with specifically designed components that take advantage of the improved airflow and further optimize the volumetric efficiency for better engine performance and faster lap times. When paired with our WORX Stage 3 ECU tune, or your own custom tune, the results are instantly noticeable. The high-quality carbon fiber and high-strength polymer construction provide a premium build quality that you won't find anywhere else. Designed and manufactured with uncompromising quality, this Ninja 500 Airbox is unlike anything else on the market.

Have you already purchased a WORX Ninja 500 Tune and want to upgrade? We'll provide a free tune reflash if you've already purchased a Stage I or Stage II tune from us before and can send in the same ECU.

The WORX Airbox comes pre-assembled, therefore we are not able to substitute items or customize the airbox or velocity stacks per order.
