About this part

Product Details

The Big Gun Rev Box is built with an advanced timing curve that changes how your engine performs at higher speeds. This part is a direct plug-in replacement for the stock CDI box on your 2001-2012 Yamaha TTR 125, LEX, EX, or LX models. It's a well-built option if you're looking to get more out of your machine without the high cost of some OEM replacements.

By increasing the overall RPM limit, this rev box allows your engine to rev higher than it would with the stock unit. The advanced timing curve also contributes to improved performance, especially as you push your TTR 125 towards its limits. Installation is straightforward, as it's designed to connect directly to your existing wiring harness, meaning no complex modifications are needed.

Keep in mind that this part is not CARB approved and cannot be shipped to California. It comes with a 6-month limited warranty from the manufacturer.
