The luggage rack makes the R look much better in the rear with that fender that sticks out. I agree it should be standard on the R as well, but it is not. The part new is like $270, so that and the other items on the GS is what makes it so much more. I found a take off GS rack for about $220 shipped, so jumped on it. I like the way it looks, but if you have the Hepco & Becker bags, you need to use the GS C-Bow brackets, two different ones between the R and GS. I already had them, so I just used a 1" square spacer I made. This also clears the longer USA turn signals to the side bags.
