I am contemplating buying a 2018 Street Glide Special, but before I do I wanted to know what solo seat luggage rack options are available. Has anyone ever used the luggage rack that sits over the fender (and not attached to a sissy bar)? Specifically, how does your luggage attach to the rack and is the luggage far enough away from the saddle bags so if you hit a bump the luggage won't scratch the saddlebag?
