So, bottom line, what specifically, could be the risks.  The wobble, of coarse, is one.  I would think there really would be a very high risk of loss of control, but that aside, what about damage to the wheel or the rest of the bike.  Stealer advises estimate of $150, parts and labor, just to swap out  the bearings.  I'm hoping there won't be any other damage discovered.  I too think wheel bearings should last 100k miles.  Failure of this "non-maintenance" part, so potently dangerous on a motorcycle, shouldn't happen very often, but I don't know how often it really does happen.  Any guesses?
