Honda Scooters - Honda Motor Scooter News, Specs, Prices

Ok, so i've been looking at the Honda Metropolitan. The price is great, and it's under 50cc so I won't need to get my motorcycle liscence (even though I plan to). My questions are these.
1.I'm not seing a weight restriction, or at least limit.
I'm 5'10" 185. My girlfriend is about 5'6" ,5'7" and I would say 115 (at least I think). Would this be too much for the tiny motor to handle?
2. Would I be able to ride this thing on the streets, or even with a passenger?
3.Any advice for a better choice?
I
'm just trying to figure out my budget (poor credit and all),and i could afford to put away about 400 or so a month to save towards this thing.
Your help is greatly appreciated
Thanks in advance
