If you're wanting a scooter depending on your preferences, I'd suggest the Yamaha Zuma. The older 50cc bikes were 2 stroke, people love them and they're tons of mods out there for them. A lot depends on the roads you'll be traveling and the speeds on the roads. A 125 might be more practical, I think the Zuma 125 is 4 stroke though.
I'm surprised no one has mentioned the Piaggio Typhoon 125cc. It's a cool looking "dual sport" style scooter. Larger wheels for both paved and not so paved roads. They just recently introduced the 50cc but it looks like it's more suited to paved streets judging by the tires on it from the factory.
I would have suggested a Rattler 110cc from Genuine but they've discontinued the bike a while ago, you may be able to find one used or at a dealership. They were 2 stroke, I've heard mixed things on them so I'd suggest doing some research on the Modern Buddy website.
Just a few bikes I thought I'd toss out there.
