2000 Honda Shadow 1100 AERO. Absolutely love my bike. Has stock Honda seat, which is OK for me by myself. I have finally talked my wife into going for some summer rides. Just wondering what is a good two-up seat for a good price? I hear Mustangs are great, but not cheap. Any others? Basically a seat that will allow two people to ride without fatigue for a few hours at a time, between gas fill-ups. Thanks !
