There's an old, tired but true saying in the world of scooter jocks that goes like this;
"the only real difference between a good case of VD and a Sportster is...that IF you really had to - you could probably find a way to get rid of your VD!"
FWIW - Sportys make an OK - second scoot but they're a piss poor, first ride for a newbie.
Give her a break. She obviously didn't know it was a dirt bike.
