I don't know how anyone can ride on the back of a liter bike for more than 20 miles.
I'm all of 5 foot 2 and my legs cramp up so bad after 20 miles I have to get off of it. Ergos for those bikes are for midgets only.
When I do ride, which isn't often (ass is waaaaay to wide

) I put hands on the tank for braking and hands resting on his back when traveling.
But, because I mainly ride my own, I lean before he does in anticipation of a curve. He asked if I wanted to pilot, cause obviously we weren't going around the curves soon enough.
