What are the odds of having a motorcycle accident?

100%... But it's a matter of how bad. Considering the percentages, almost everyone I know has downed a bike... but having a real accident, I don't know the exact percentage. Although of the reporting 2400ish accidents in 2007, there was some type of injury in 2200ish cases where the person had to go to the hospital. But I suppose this could be a light bump to the head too.
