I bought this beautiful tank bag just before the winter. I just find out it will not fit on my big VTX tank but I can not rerurn it any more. It is never mounted on the bike but I did throw away all the packaging materials. It is very well designed half-hard case. It keeps its shape even when it is empty. Both the magnetic mounting base and the map pocket are detachable with zippers. Here is manufcaturers description:
