I had one of the luggage mount plates on my original subframe break off. I then installed a R100GS subframe and it's been fine to this day. A friend of mine had his R100GS subframe separate behind the grab loop, but it was due to some VERY rough roads, VERY heavy loads, and a lot of play in his luggage mounts. They knocked a lot and led to a fatigue failure
