Ride the R1200GS and it goes well with the bike. Someone complained that it didn't fit their sport bike but looking at the picture and even reading the description that it was a larger ADV bike I would put that on the buyer but they gave the bag anyway 1 star. The bag is well made, durable and with strong attachment points. Haven't tested it in the rain yet, but experience of what works and what doesn't over the past few decades of riding tends to protect it from the heaviest downpours. The secondary roller function under the zip gets the job done. Not sure if it will withstand a long dive underwater, but I ride a motorbike, not raft. That's what they make bags for, as we all know.
