If got 63k out of the OEM bearings, wouldn't you get the same from the dealer?
What is actually wrong with your bearings ? How have you deemed its time to change them ?
A friend of mine just bought a much newer SV and what I notice is that my bike has significantly higher rolling resistance. My chain is new, clean and well adjusted, brakes not dragging, tires inflated to the specs.
When I installed new tires this summer I checked all bearings and all looked okay. There was no play I could feel with my finger. Repacked drum bearing, the other four are sealed...
Also noticed some notchiness lately at small speed with a passenger at the back. Almost a sensation of a kinked chain but the chain and sprockets are new... Not certain its from bearings but decided it's time to change based on mileage alone anyway.
bearings need to have radial play or they would seize, from what you are describing it might not be the bearings, but might be seals or over torque axle etc. Brakes will always drag as there is no real provision to pull the pads back.
from what you are describing - its not bearings. Have you put all the spacers back in their correct spots?
I've seen bikes with 20k and destroyed bearings due to poor tire install (2nd set of tires put on by me), but I also take care of high mileage bikes 60-80K that have mint bearings. My street bikes all over over 60k on them, all bearings mint.
