My F700GS came with the option package that included the Vario bag mounts. Last night while at the Seattle Motorcycle Show I received a coupon for 30% off any BMW accessories over $500. So, my question is, are these vario bags any good? I don't/can't go off-road due to a back problem so I'm not too worried about banging around. I loved the BMW cases on my old R1150R, are these as good?
