You know, if you spend just a little more $ and buy a bigger scooter......you can just ride it and not have to figure out how to make it go faster incrementally. ......
So many here struggle to make a 50 go faster - and are not always happy with the results.

This makes sense if you ignore everything the OP wrote about why they want a 50cc 2T scooter. There are a lot more costs and licensing requirements that go into getting one one the road in a lot of countries than just the price of the scooter. In Ohio, like in California, you need the same Motorcycle license for a 50cc scooter as you do for a Hayabusa. You can get your license on a Vino 50, and then go buy that Gold Wing as your first bike. So it makes no sense to buy a 50 in States like Ohio or California. In a lot of places, the rules are different. Think about how much better the scooter scene would be in the US if a State like California had a moped law like most of the Eastern States.
As far as restrictions, Kymco usually does the boss and the CDI. in any country where they sell them, the guys who sell them know how to derestrict them completely. It's part of the job.
Another decent scooter to check out is the Keeway Goccia, if they have it there. I liked it a lot more than the Agility 50.
