I bought a used riders backrest like the one in the link. It just flops around when I am not in the saddle. I had a Road King contoured backrest and it had an internal spring under the backrest leather by the mounting arms that I presume kept from flopping forward or backward when you dismount. My question is shouldn't the backrest in the link have this internal spring. Thanks
