If you are talking about the one that looks like a drain plug it's the crankcase drain. It's to drain out any oil left in the crankcase. If you plan on doing your own maintenance on your bike I would highly recommend getting a proper service manual. It will answer questions like you just asked.

First thing I would do is find out what insurance will cost you. If you just got your motorcycle license a Ninja in the 600 cc class or higher could cost you a lot more then you can afford. You don't have to buy the bike first in order to get an insurance quote.
If insurance is not an issue...
