Abstract: Saddlebag support bars and mounting plates for supporting saddlebags on a motorcycle. The mounting plates are flat members with a first end having a reduced thickness to cooperate with the bracket of a motorcycle backrest. The mounting brackets include a pair of bolt-receiving mounting holes for mounting the support bars, one of which has a cut-out area on its underside to receive the head of a mounting plate attachment bolt. The support bar includes a modified U-shape projecting rearwardly and outwardly from a respective support bar.
