Description We love the Yamaha YZF-R3 / MT-03 platform, but we found that the 321cc engine has more to give than what the stock ECU will allow. That's why we unleashed our championship-winning WORX Racing Division on our very own 2025 Yamaha YZF-R3 and MT-03. After hours on the dyno and countless laps around the track, we've put together a quick and easy way for riders to make the most of their aftermarket full-system exhaust upgrade. By capitalizing on the improved airflow provided by the full-system exhaust, this tune upgrades a wide variety of parameters to provide increased horsepower and torque across the entire rev range. With a 5% increase in peak power and 5-8% increase in torque in the top end, this tune provides real-world power gains that can help you seperate yourself from the pack. This tune also optimizes the Yamaha by adjusting or disabling a wide range of parameters that aid in overall performance and operational improvements. Give your Yamaha more power and feel the difference with every twist of the throttle! This tune was specifically designed to work with aftermarket full system exhaust and the stock air filter, although aftermarket air filters can be used without negative performance effects. AFTER TUNE: Please note that a temporary check engine light will appear after flashing due to being powered out of the motorcycle. Don't stress, the check engine light will clear itself after two ride cycles and does not affect the performance or functionality of your motorcycle. NORTH AMERICAN MARKET ONLY: Please keep in mind that this is only available for North American market Yamaha YZF-R3 motorcycles ONLY. All orders placed outside of the North American region will be canceled.
