Wow, Westchester. Being from that part of NYC myself, I can say that it is not part of NYC. White plains, maybe.
Matisyahu is from White Plains. I didn't know that until recently.
Anyway, Mark, the Derbi you're getting sounds awesome. It is also not really like mopeds except for the 50cc, two-stroke powerplant - everything else (starter, fairings, brakes, frame, lights) is different. I'm not sure anyone on this site this year will be able to answer your questions.
Well, okay, technically this post was an answer to your question. It wasn't a very good answer, though.
P.S. - If you're getting a second hand bike that has a starter motor but no ignition switch you should consider that it might be stolen.
