Happy to join this group after lurking for a while. Just picked up a budget 2003 to feed my Goldwing curiosity. The previous owner had gone double darkside with it. It rides fine and after a couple hundred miles, the darkside didn't yield any major surprises. I'd like to see how it handles with regular motorcycle tires, though, and can pick up a pretty inexpensive rear wheel and tire. My question is will the 130/70-18 M/C 63H that is now on the front induce any handling irregularities if I put a standard 180/70R16 on the back?
