Newbikers let me start by saying, Welcome to our world, Enjoy the ride. Also be careful these things are addicting. If you like to "tinker" then these engines are perfect for you. If I'm not mistaken these engines are the same ones you find in those scooters, minus the transmission and the other stuff. To answer your question of transportation. They can be great just baby them and take care of their needs and you'll be just fine.
If your ever coming down to Sc. give me a holler, we'll ride together.
