In my opinion if you don't have any experience on a bike, wait until you have some experience. Get a dirt bike or something first. Motorcycle should not be your first vehicle. You'll probably end up killing yourself. I started riding on an old XR100 then moved to an RM85. First street bike's going to be an DR-Z 400. From there I'm going to move on to a street. Problem with street bikes for me is finding one that I'd actually enjoy owning.
