Put a big set of bags on my 1150 GS. Very happy and really look good with the bike:
Lots of room to access the rear end without taking off the side bag. Might even look into getting a full size left case:
Top case sits a bit lower on the 1150 than the 1200 but that's not a big deal for me:
Gives the bike a nice profile:
Very nice, robust product. And of course, great customer service.
