If I were single I would definitely pick one up...man, what a machine it would be for a single guy.
I never thought of it before, but I believe you are spot on. Everyone loves going for a ride on the rig.
For years I have said if I split up with my wife, I would buy one of those, get an aviator hat and goggles made for a dog passenger, then make a map of nursing and massage therapy colleges across North America and just ride around to them, asking for directions and getting laid.
Now that they make them with all disc brakes and EFI...well, it's not making it any less tempting.
