I don't have the rack for the top box but I do have the Motech side plates to mount Givi bags on my RS. I like being able to easily take them off; there are just three quarter-turn fasteners on each side. I didn't really care for the relocated turn signals so I mounted some smaller indicators in the stock location.
Here's a pic of the bike with the bags on
