Pannier Racks for the BMW R 1300 GS / GSA The Outback Motortek pannier racks for the BMW R 1300 GS / GSA are the most universal and functional side pannier frames yet, allowing simple, secure mounting of hard panniers, soft luggage and accessories. We offer both Standard and X-Frame pannier racks. The difference between the two is that the Standard frames do not feature the extra X-Bracket mounts and the tabs welded on all four corners.
