I ordered this bag for my Honda VTX /National Cycle 2-UP Switchblade windshield. It doesn't have a center hole on the windshield so I just measured where the 2 most center holes are on the windshield and made two holes in the bag so the bracket on the bag fits over the horizontal chrome windshield bar and mounted this bag. Before I did this I "curved" the bag a little to the windshield curvature.
I did also add my own "lining" including a couple of vertical pockets, one to put my garage door opener in and the other to keep paperwork in.
Why did I get this from FCL? Because in the past I have numerous other products from FCL, and have always had outstanding customer service.
