I'm thinking about getting my first motorcycle but I'm worried about keeping it in the apartment parking lot. Any advice?

I live in a poor area and there are a lot of troublesome kids in my apartment complex. I don't want them climbing on it or touching it, ultimately risking it falling over. Do any of you have experience with this? Any tips or advice for dissuading people from touching it? Should I just not get a motorcycle if this will be a problem?
