Yes indeedy, somewhat sobering.
Manual says pull apart, inspect all parts while at the same time saying the bearings can't be removed without fkg them up ? .... manuals .....
I can't see why you can't treat them like the bearing lube n the final drive, pull the seals and coat them with the aid of a spatula device.
Prob there is you need a factory tool for frame alignment in reassembly, cheap enough in the USA but tack on $130 for shipping to NZ

.
Have you done the steering head bearings yet ?
