I have noticed most girls on the back of sport bikes are good looking. Their looks are dircectly propotional to the guy they are with though. Better sportbike, he makes more money, shes prettier. Dude doesn't look so good, his lady follows suit.
So what do most of you wear? I'm looking at getting my first bike, an M50, and I'm going to get a jacket and make my wife do the same to ride on the back.
