How much will this hurt

SWMBO was driving to work today when there was 'a bang and a cloud of 
smoke' and a 'bit of a loss of power, but it drove OK, but there's a 
funny noise'

2 x AA men have looked so far
1) Clutch has gone and hit gear box (! nice to know they are as ever 
well trained. Last one I had refused to take anything off the bike as 
'fairings can break')
2) Gearbox is gone.  Not quite sure how it can be 'gone' since it still 
changes gear and she managed to drive OK for several miles.

My money is on either bearing or gear disintegration.

Other theories? Hideous cost projections?
