I have been riding most of my life; can't explain it but it also has the added benefit that my wife and I have "it" in common. My wife doesn't nag, she doesn't find me things to do instead of ride, only complains about me riding when she can't go, her bike is louder than mine, and when we were younger and rode two up she never compained about the rear pegs, the weather, the straight pipes, the pillion, or having to pull maintenence enroute along the side of the road.
