That's one of the few things with which I have some experience. I can confirm that Luigi didn't want to get his hands sticky, as I discovered what appeared to be a mist of Vaseline on all my shock linkage and swingarm(!) bearings. Once the rear wheel is removed, access to the shock linkage is facilitated by removing the exhaust can. All the bearings are similar, of the needle type, and should come out easily after removing their respective bolts. BEWARE the loose needles! They will fall everywhere as there is no grease (guess how I know this) to keep them in their housing.
Mr. Roper's advice compelled me to take the plunge and look at my swingarm bearings "while I was in there". That was an order of magnitude greater in complexity, at least for me. GET A MANUAL. Removing the swingarm includes removing the side/foot peg plates, which happen to locate the center stand! You must support the frame elsewhere. I hung mine from straps and my ceiling. You must have a special notched socket wrench for the swing arm bolt. But it was worth it, as the tapered roller bearings were just as dry as the shock linkage needle bearings. The left side had just started showing some corrosion, but I caught it in time.
Hopefully, knowledgeable folk from Australia, much more capable than I, will weigh in on this. My best advice: GET A MANUAL.
