Yep......they make a 200MM rear tire kit for the Sporty......I'm looking at it as I type.
I got the seat changed to a solo....here's a pic:
I swapped both bikes to solo seats cause I don't want no chicks on my scoots...Now when they ask for a ride, I can say 'sorry, no place for you to sit"
But you know, JD....I'm thinking if I was to let a fat chick sit on it till i cleared the traps and then let her fall off, I could launch better.....Whadda ya think?
