To add to my post I am not saying I am bullet proof or some cocky I can't get hurt ridder... I was probably lucky in a lot of close calls, etc. but I have always had a lot of respect, etc. for cycles/quads.
I started out on a Honda trail 70cc bike you know the ones with the fold down handlebars people used to put them on the front of there rv's, then 80cc (XR, XL), then 175cc trail (RS, PE), and then 125cc racing type bikes (RM, CR).
