At 14 I had a minibike and would ride all over town with a few friends, being careful not to get caught by the local PD.
At sixteen I got to ride my cousins Honda 175...it was the first motorcycle I road.

When I hit highschool I was able to get a Yamaha RD 350 after much wrangling and convincing of my father to allow me to get it. I felt bad shortly afterwards when he had to go to the hospital and the guy in the bed next to him was admitted after a bad motorcycle accident.
Just a little difference from my first bike to my current R3.....
