I used to ride a lot until I was about 18. Had a Kawasaki rice burner. I had 2 friends die riding in a year (one right in front of me) and a third blow out his knee on a bike and lose a football scholarship to Michigan. That was enough for me. I'm sure Peaches will be by to give you some motherly advice as well.
She had her own bike accident as well. I doubt anything I say will dissuade you from buying one but I will never ride again.
