I have been on a street bike once in my life. My grandad's Honda 1100 something. I ended in the ditch, but didn't fall. After that I decided to stick to the dirt.
I use to ride motocross but sold my bike when I moved off to college. Here is a pic of me from a few years ago on a 1994 RM125. This was my first real motocross bike. It was Ezra Lusk's supercross practice bike from the year he won the East Coast Supercross Championship. I need to look and see if I can find any newer pictures.
