How comfortable did you feel riding on the 250cc bikes that they had at MSF? You can get what you want, but recommended is to work your way up. Experience on a closed parking lot on a 250cc is way different than riding on the street. It'll take a couple thousand miles before you start getting used to people not seeing you, and all the added lessons you will learn while riding on the street. Rather than getting a 600cc and having to deal with 2 things: learning that 6th sense of street riding and learning to control the power on a 600cc bike, you should get a smaller bike to learn on. You only have one life to live.
