All the systems will be dealt with on this bike and I've chosen to begin with the rear portion. The swingarm has some staining on the anodized finish, probably from leaking battery acid in the past, so that will need refinishing. To get to that item just about everything nearby needs removing, which will allow cleaning and any needed refurbishment.
The rear brake action, for example, is sluggish so those components will need rebuilding. The previous owner reports that the OEM shock absorber has had a rebuild, though I have no real particulars, but it feels fine and even a bit stiff on the road, so I'll need to make a decision on whether it stays or goes.
