Do you mean "shimmy", where just riding along, the front end will start a rapid, high frequency well, wobble? As opposed to the lower frequency wobble you get say from a bent rim?
If it's shimmy, then IME all sorts of imponderable little things can cause it. I've had shimmy come, or go, after swapping tires; after putting on a front load; after adjusting saddle and bar. I'm not saying that these changes caused the appearance or disappearance of shimmy, just that it occurred or went away with such little changes. Right now, knock on wood, the '2003 Curt road custom doesn't shimmy; it did last year in straight lines starting at about 15 mph, if I took both hands off the bar. What changed? Well, I put my Chauncey Matthews lowrider racks back on. And the shimmy started when I swapped 35 mm Kojaks for the Elk Passes. Or something.
