That is the type of bracket sold by DynoJet to install a map switch.
That does not look like the kind of switch they use however but you can use any kind of ON/OFF switch you want.
Does the bike have a PC5 or Ignition Module? If it does check to see if there are any small wires going into the open ports in the side. Two would lead to that switch if it is Map switch or AutoTune switch.
If this is any switch connected to your PC5, I would not ride unless you know what feature it is connected to and if that feature is enabled in the module. Most likely, it would not harm anything if it is a race map (actually less agressive fueling/timing) but who knows what it is. You'd need to get a laptop out on the bike with the Control Center software and view the mapping.
Or it might be a nitrous switch. The push button looks like it's probably an intermittent which would be the thing for NOS. LOL better check if you got that!
