Pardon my ignorance, but at 6000 miles, what maintenance would have been done? An oil change maybe? The first major service?
The wheel bearing having gone out leads me to wonder whether that odometer reading is correct?
Most things would probably be as much due to time and neglect as they are mileage.
Oil change
Antifreeze change
Valve Adjustment
Belts changed (check tensioner bearings)
Fuel filter change
In-tank fuel line replacement
spark plugs replace
Check alternator wiring for burning/brittleness
Fork oil change
Steering head bearings greased
Change fluid/bleed front & rear brakes + clutch
Check clutch slave cylinder for leakage
Grease swingarm bearings & rear suspension linkage
Change rear wheel bearing (check chain for wear as over-tightening might be the cause of the bearing failure)
Other possibles: cam seals (there are 5), flaking rockers.
So what would I do?
Buy/rent the tools you need, get a factory service manual, and the Haynes manual. Pull the motor or at least strip the bike of all its bodywork. Take your time and go through everything. Your time is free, the mechanic's is not. You will spend more than the cost of taking it to the dealer, plus you know it is done right and complete (even if it takes you a couple of times to get it right).
The only thing on the list above you
might want the dealer to do is the valve check, rocker check, cam seals, and belts. Everything else is pretty easy DIY. And if you take it to them stripped down and drained of fluids, your bill for those items should be less.
