ABSTRACT:
A motorcycle having a number of cooperating protective features to protect riders against injury in high speed crashes or other accidents. A motorcycle of the usual basic configuration, having a pair of wheels in tandem with a motor therebetween connected by a basic frame which supports at least one rider's seat assembly and a steering assembly for steering the front wheel is surrounded by a cage assembly of high strength, light-weight tubing fastened to the frame and forming part of the frame. The steering assembly includes handlebars which are padded and mounted on a folding mechanism to move forwardly as the rider moves forwardly into contact with the handlebars upon front impact. The seat assembly is in the form of a padded "bucket" type seat with sides that extend partially around the rider's sides. A padded body restraint surrounds the front of the rider's torso and includes side portions which extend around into contact with the seat sides to completely surround the rider's torso. Adjustable, padded headrest and collar devices are provided to limit head movement in an accident. A shock absorber is provided to absorb impact energy causing the seat and body restraint to move forwardly upon frontal collision between the motorcycle and another object. A retrieval means returns the seat and body restraint to the original position after impact forces are absorbed. An anti-somersault extension on the front of the cage is provided to prevent the motorcycle somersaulting after a frontal impact.
