An adjustable back rest for a motorcycle comprising a carrier assembly connected to the frame of the motorcycle, a back plate assembly pivotally attached to the carrier assembly and positionable at an inclination angle, and an extensible slide connected between the carrier assembly and the back plate assembly that extends or retracts to thereby adjust the inclination angle of the back plate assembly and then is secured in place to position the back plate assembly as desired. A pillion rest is attached to the back plate assembly and is angularly adjustable by positioning a plurality of bar links connected between the pillion rest and the back plate assembly. The carrier assembly can be positioned and secured to the motorcycle frame to provide back rest support for the driver, or it may be positioned and secured to a cargo carrier attached to the frame to provide back rest support for the passenger.

1. An adjustable back rest and cargo carrier for a motorcycle, comprising: a carrier assembly connected to a motorcycle frame; a back plate assembly pivotally attached to the carrier assembly and positionable horizontally and at a first inclination angle; and an extensible slide connected between the carrier assembly and the back plate assembly, the slide having a first portion and a second portion that slidably engage each other and a fastening mechanism to selectively release or secure the first and second portions relative to each other to allow the slide to be extended or retracted to a desired position and then secured in place to thereby adjust the inclination angle of the back plate assembly from a horizontal position to said first inclination angle, and a pillion rest attached to the back plate assembly, the pillion rest being angularly adjustable relative to the back plate assembly, whereby said back rest plate assembly may be positioned horizontally as a cargo carrier and inclined to a first inclination angle as a back rest.
