It's a pretty common problem with Goldwings. You can spend ages and many dollars chasing down the cause - front wheel bearings, steering bearings, steering torque, cupped tires, worn tires, swingarm pivot torque, swingarm pivot bearings, rear wheel bearings. Or you can just keep your hands on the handlebars. :)

Plus tire pressure and brand of tire. Whenever mine did it it was at 30mph or less.
Enjoy the ride. They are all good, just some better than others.

1st thing to check is the front tire. Is it new or well worn? Well worn might be good time for a new one. Air it up to 40 psi. I replace mine because it was close to the wear bars and I had a bad wobble at slow speeds. After the dealer put a new E3 on there was still a tinybitof wobble, not much, but noticable. I checked the air pressure and the 'mechanic' only put 32 psi. Aired it up to 41 and wobble was gone. Never trust these dealerships to do things right. Always check the psi after you get it back. If this dosen't correct it then check the items mentioned above.

It is the nature of all two wheeled motorcycles to develop a wobble at some speed. It is inherent in the design.
It is the task of the designer to attempt to minimize this, and to try to put it at a speed that will do the least harm. The easiest way to minimize it is to make a very stiff chassis, but with all the bags and extra gear on these bikes that kind of stiffness would require that they weigh many times more than they do. The aluminum perimeter frame was still in it's infancy in the early 80's so the designers choose the geometry that would give nimble handling for such a big bike while bringing the tendency to wobble down into the lower speed range. I'm sure they would have loved to eliminate it but were forced to compromise.
While they will all do it to some extent, all the things mentioned by the others above will affect it. I would look at tires first, then wheel bearings and steering head bearings and pre-load. My 84 Int. changed drastically for the better with new steering head bearings. After a while the wobble came back a bit and when I re tensioned the steering head it almost went away again.

As our esteemed Moderator pointed out, our hands act like dampers on the bars and the best advise is to keep your bike maintained and adjusted and to keep your hands where they belong.
