Thinking about what bike to start with before thinking about what training to get is kind of putting the cart before the horse. I would strongly strongly suggest to start with a good riding class. MSF (Motorcycle Safety Foundation) training are really good and they offer classes in every state. Here is the web site
Motorcycle Safety Foundation They have basic and advanced classes. For the basic class they will provide the bike. Believe me you will learn a lot about riding a motorcycle and you will also learn about your own riding skills. After the class you will feel more comfortable at choosing what bike will suit you best. It is crucial that you get the right riding education before hitting the road on your own. It is a matter of life and death, as simple as that. When you are ready to ride on your own always assume that you are invisible to others because most of the time you are. Also always always wear good riding gear and of course a good helmet. Actually I just came back this afternoon from spending the week-end at the bike fest in Myrtle Beach SC. I could not believe how many "riders" were riding in sandals, tee shirts and without an helmet, yes without an helmet because on South Carolina wearing an helmet when riding a motorcycle is not mandatory.
