Big Gun 17-19 Honda CRF 250L/M/Rally Power Box

With this Big Gun TFI Power Box, you get the module itself, designed to plug directly into your Honda CRF 250L, 250M, or 250 Rally from 2017 to 2019. This unit is built to give your EFI system a noticeable performance upgrade. It works by fine-tuning how your throttle inputs are translated into fuel delivery, making the engine feel more responsive and powerful, especially in the mid-range where you often need it most.

Installation is straightforward thanks to its plug-and-play design, meaning it connects directly to your bike's existing wiring without needing to reprogram the stock ECU. You can make on-the-fly adjustments using the integrated buttons on the faceplate, so you don't need a computer to dial in the EFI settings. This third-generation technology is built tough with weather-resistant sealing, ready to handle the rigors of off-road riding. It's a popular choice when you've added an aftermarket exhaust and want to get the most out of your engine's breathing.

This power box is designed to enhance your riding experience by sharpening throttle response and smoothing out power delivery. While it's not CARB approved and cannot be shipped to California, it offers a simple way to unlock more performance from your CRF 250.
