Big Gun 19-23 Honda CRF 450L Power Box

If you're looking to get the most out of your 2019-2023 Honda CRF 450L, especially after adding an aftermarket exhaust, this TFI Power Box from Big Gun is a solid option. It's designed to fine-tune your bike's electronic fuel injection (EFI) system, making a noticeable difference in how the engine performs. You'll find that the throttle feels more responsive, and the power delivery becomes smoother, particularly in the mid-range where you often need it most.

What's great about this unit is that it's a plug-and-play module, meaning it connects directly into your bike's existing wiring without needing to remap the stock ECU. It uses third-generation technology and has integrated buttons on the faceplate, so you can easily make adjustments on the fly without needing a computer. The construction is rugged and weather-resistant, built to handle the kind of conditions you'd expect to encounter off-road, and it installs in just minutes.
