Abstract: A motorcycle has a front part and a rear part, the front part including handlebars and a handlebar stem with which there is associated an electronic damper controlled by a control unit controlling the action of the damper on the handlebars, provision being made for a device detecting the angle of rotation of the handlebars and the velocity of rotation of the handlebar stem within a handlebar head of the frame. The control unit includes a first block which receives data on the velocity of rotation of the handlebar stem and which on the basis of such velocity determines the presence of oscillating or weave movement of the motorcycle or a wobble movement of the handlebars, the first block of the control unit being connected to a second block and a third block of such unit which alternatively generate a control signal intended to damp the handlebar stem on the basis of the determination made by the first block so that any weave and/or wobble movement is cancelled out.

Abstract: A motorcycle includes a frame mounted on wheels having a front and rear parts, handlebar located at the front part motorcycle speed and roll angle detector, the front and rear parts join on a frame longitudinal median plane (W). A device for detecting a vehicle moving towards the rear part when the motorcycle is moving, the device including a radar detector or television camera rigidly of one piece with the motorcycle, the radar detector rigidly associated with the rear part and following its movement. The radar detector connected to a presence and movement evaluator of the vehicle moving towards the rear part capable of determining a variable hazard indication which identifies a time to collision between the vehicle and the motorcycle. The evaluator activating warning means on the basis of such hazard indication which generate a warning for the rider's attention when the hazard indication reaches a predetermined value.
