Easiest way to find out would be to disconnect any wiring to it and try it out. If all is fine then remove it completely. Older bikes never had one, so the only doubt is if the electronics have a sneaky feature built in. Depends if that the sensor is normally switched on or off, but the test above should help diagnose that.

Your BAS has 3 wires going to it: gray, black, and green/blue. Gray is main power, black is ground, and green/blue goes to the ignition nosecone.
To bypass, you need to cap the gray wire. Then you will connect the green/blue wire to black (or other suitable ground).
Just unconnecting it will not allow the bike to run as it is a safety mechanism. The green wire to the module needs to be grounded for it to be in a "run" state.
How it works:
There is a little magnetic ball in a v-shaped groove in the sensor. The power comes in to the BAS from the gray wire in to a hall effect sensor. It normally flows through the sensor and eventually to ground in the black wire so long as the magnetic ball is where it is supposed to be. The green wire is output from the hall effect. It runs through a fancy circuit (details HERE, not for the non-electrically inclined) that kills the ignition (I'm guessing by grounding it) when triggered by absence of the ball where it should be.
