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. See the Tune Details tab for more information or CLICK HERE to get the free reflash.

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

Tune Features

  • Stage 3 WORX Tune specifically developed for the WORX Airbox and the following parts:
  • Increases rev limiter by 300 RPM
  • Disables O2 sensor FI code
  • Disables PAIR/AIS fault code
  • Disables EVAP fault code
  • Disables decel fuel cut
  • Decreases setpoint for cooling fan startup
  • Optimizes fuel maps
  • Optimizes ignition timing maps

Premium 91-93 octane fuel is required for expected results and safety against knock.

Requirements

It is your responsibility to ship an undamaged and unmodified Ninja 500 OEM ECU to our facility in Lake Helen, Florida for tuning. The ECU must be properly packed and free of any damage or contaminants to be tuned properly. Once the ECU is tuned, we'll ship your newly flashed ECU back to you for installation. Please note that if your "Check Engine" light is on previous to an ECU tune, the light may remain on after the reflash and will need to be cleared manually.

If including an ECU flash in your order, the WORX Airbox will ship with your WORX tuned ECU.

If your ECU does not meet the requirements required to be flashed, we will not be able to perform the programming required to take full advantage of the other components listed on this page. It is your responsibility to confirm that your ECU is unmodified and undamaged before purchasing.

If you have an ECU that has been previously flashed with a TST WORX tune and want to upgrade your Ninja 500 with this airbox, please CLICK HERE to add a free reflash tune to your cart.

Installation

 
Q: Do I have to do any modification to my bike or airbox?
A: There is a small tab that is attached to the frame that will need to be either bent or removed entirely, depending on your preference. On non-ABS models, this tab is not used for anything and is typically removed by most racers. No modification is required to the stock airbox as this is a complete replacement of the airbox assembly.

Q: Can I use a stock air filter or other aftermarket air filters with this airbox?
A: The air filter that is included with this airbox has been specifically designed to fit within the reshaped design. The stock air filter or any other aftermarket filter that has been designed for the stock airbox will not fit.

Q: How often do I need to clean or replace the air filter?
A: We recommend checking the air filter for visible debris after each race weekend. You can clean and wash the open cell foam filter and re-oil it with your preferred filter oil. If you decide you need a replacement filter, click HERE to order a new one.

Q: If I already have a WORX Tune on my Ninja 500 ECU, can I get the Stage 3 Tune at a discount?
A: Absolutely! We actually offer a free reflash of any previously tuned ECU right HERE. Just pay the $15 shipping and input the original WORX Tune order number and we'll get your ECU reflashed so you can take full advantage of the improved airflow.

Q: How long will it take for me to receive this once I order it?
A: Our handling time is 1-2 business days, and the shipping time varies based on the shipping method selected. To learn more about shipping times, please see the articles in our Terms & Conditions regarding domestic and international shipping here.

Q: I'm located outside of the United States. Will I have to pay duties on this item?
A: Some countries charge additional fees when a package is imported and delivered to the recipient. We have no way of knowing or estimating what these fees will be. It is the buyer's responsibility to cover these additional costs.

Q: What is your return and warranty policy?
A: Please read over our policies thoroughly on our terms and conditions page BEFORE making your purchase.

Hyperpack Bundle for Yamaha MT-03 2020+
This looks very clean on the bike. I am not a very hands-on person and I could install it very easily. Customer support was great too!
