Push your Honda CRF or XR engine further with the Big Gun Rev Box, which raises the overall rev limit to 10,000 RPM and uses an advanced timing curve to enhance high-RPM performance. It’s a simple way to remove the stock CDI’s RPM restriction and make more of your engine’s powerband accessible.
Installation is straightforward thanks to the direct plug-in design that replaces the factory CDI box. Backed by a 6-month limited warranty, this is an easy performance upgrade for riders looking to extend their Honda’s RPM range.
Features:
- Increases overall rev limit to 10,000 RPM
- Advanced timing curve
- Easy direct plug in replacement to stock CDI box
- 6 Month Limited Warranty
