The disclosure sets forth a roll-bar structure for a conventional motorcycle configured to provide both forward and aftward protection as well as side protection. The basic embodiment comprises dual spaced apart longitudinal tubular, metal members of inverted U-shaped design, the lower terminuses of which are oppositely fixed to both the front and rear of the motorcycle mainframe. Other embodiments include an articulated rear-half assembly which can move fore and aft according to the position of the motorcyclist, a longitudinal roll-bar configuration appearing substantially H-shaped in side view, and a combination of an inverted U-shaped roll-bar and an H-shaped roll-bar.
