Abstract: A backrest device for a motorcycle rider that may be positioned forward to provide a backrest for one rider who is the operator of a motorcycle, and may be swingably repositioned to provide a backrest for a passenger who rides in tandem with the operator on the seat of the motorcycle. The backrest device has a cushioned backrest and a single pair of arms pivotally secured at opposite ends to the backrest and to an upright of a sissy bar. In a forward or extended position, a snubber prevents further backward tilt of the backrest. In a rearward or collapsed position, locking means secures the arms to the upright of the sissy bar.
