Damaged or overtightened steering stem bearings can cause all sorts of handling ills as well.

I copied this from a post from Jeff Saunders (owner of Z1 enterprises)
Motorcycle Wobble Causes
There's a LONG list of potential area that can cause this.
These are not in any particular order
Wheel bearings
Steering bearings - repack grease, check tightness
Swing arm bushings/sleeves/bearings - replace if worn, repack grease
Fork springs aging - check spring length
Unequal fork oil - if seals leak, then your damping can be ineffective
Rear shocks aging, damper leaks - if you have oil leaking from the seals, the damping is toast.
Worn Tires/Mismatched tires/tire pressures/wrong size tires
Wheel alignment - don't trust the chain adjusters - I visually align the wheels.
Bent rims/broken spokes - get the wheels off the ground and spin them - check for runout / damage
Front disc warped - check for runout
Steering & swing arm bearings are very common problems, but so are tire issues (pressure/mismatch) and wheel alignment.
