as far as i know the bike needs a battery because the alternator needs power to make power. makes sense to me that it shouldnt need one after starting but i dont think it will run without one.

Below around 3000 rpm the charging system will not put out enough to run all the electrical load thus it pulls the additional load from the battery so yes, you need a battery and may have a charging problem.
