Installing shiny new rearsets can improve comfort and performance, but the aftermarket foot pegs and brake pedal are not likely to be compatible with your original brake light switch. In order to keep your brake light activating with your aftermarket rearsets you'll need a new style of switch that would activate no matter what type of rearset you're using. A hydraulic brake light switch will activate your brake light as long as you are running a hydraulic brake system that uses a banjo bolt fitting. A universal motorcycle brake light switch will help keep your track bike street legal or maintain your rear brake light activation with aftermarket foot controls.
