I picked up a 750 that had been ridden about three times and 25 .. Spent a halfway. Fixing a few things,then put on about 700 miles in 26hours, it had a wore out tire and chain..which barely made it that day.
Do I regret that experience..even for a second..not a chance..
Wheel bearings? Do they spin fairly freely?.. Used them them. Can they screw up..yes....more like a slow, noisy,increasing run out death.. Worry more about tires., and check front caliper, sprockets and chain... Better yet, bring front sprocket, and caliper seal, or working caliper. master cylinder may start weeping.
Maybe try this..contact shippers a maybe, spend sometime going over it,ride it around town/hiway, then if checks out..set out. If not ride to the shipper.
