Big Gun 09-15 Yamaha ZUMA 125 Power Box

Big Gun is known for making performance exhaust systems, and their TFI Power Box is a natural extension of that focus. This module is designed to work with your Yamaha ZUMA 125's electronic fuel injection (EFI) system to give you a noticeable performance improvement. It works by fine-tuning how your throttle inputs are translated into fuel delivery, making the engine more responsive.

You'll find that installing this power box is straightforward, as it uses plug-and-play technology, meaning it connects directly into your existing wiring without needing to reprogram the stock ECU. This unit is especially beneficial if you've already upgraded your exhaust, as it helps the engine take full advantage of the improved airflow. The integrated buttons on the faceplate let you make adjustments easily, without needing a computer, and the rugged, weather-resistant construction means it's built to handle the demands of powersports riding.

This TFI Power Box is a solid option for riders looking to get more out of their ZUMA 125, especially when paired with an aftermarket exhaust. It's designed to enhance mid-range torque and sharpen throttle response, making the scooter feel more lively. Just remember that it is not CARB approved and cannot be shipped to California.
