If you stay off the throttle for most of the first year, it can be done. And I mean limit strictly to part throttle. Just don't crack that throttle wide open till you've got some good basic experience. And take the MSF motorcycle rider course. Do a walk in, since they are probably all booked for the Summer already. A couple of people usually don't show, and it's whoever showed up first to do a walk-in. Any cheap bike is a good starter, it will fall, get beat up, and take abuse. edit: There are compelling reasons to start on a 250cc, it's more forgiving of mistakes. In many European countries, the new riders have to start on a 250cc for a year, by license.
