Regarding the rear suspension drag link, I just took mine apart and re-greased the bearings and sleeves with a heavy duty industrial bearing grease I have used previously on my old GTR1000 rear suspension (which has actually got grease nipples fitted, amazing what they thought of back in the 1980's). This grease is based on Calcium Sulfonate and is resistant to water and chemicals including caustic cleaning solutions. It absolutely stops wear and any corrosion damage. Would recommend getting a grease of this type, it also works brilliantly on head stock bearings and other load carrying areas, not sure about wheel bearings as whilst it is an NLGI 2 grease it feels "heavy" for use in high speed roller bearings.
This is the one I use in 400g cartridges.
