These brand new universal custom fit black desperado saddlebags have smooth backs in order for the customer to design and fabricate a mounting system. There are 2 saddlebags, 4 5/16 x 1-1/2 fender washers, 4 3/8 x 1-1/2 fender washers, 2 locks with keys, 2 keys for locking buckles and the instructions. All additional hardware has to be purchased separately like the quick disconnect saddlebag mounting kits (recommended). Please contact me if you have any other questions and I will make sure you get the answer from my husband who purchased them.
