Claim:
1. A motorcycle suspension comprising: a portion of a frame of an associable motorcycle, a fork hinged to said portion of the frame of the motorcycle in relation to at least one hinge pin, a damper unit, positioned between said portion of the frame and the fork, comprising at least one spring and at least one damper so as to permit a relative rotation of the fork in relation to said portion of the frame around said at least one hinge pin, characterised in that the suspension comprises a load sensor to measure the load weighing on the damper unit depending on the shift of the fork in relation to said portion of the frame, and a control unit operatively connected to said load sensor, wherein the suspension comprises regulation means of the damper unit, comprising regulation means of the pre-loading of the spring and regulation means of the damping of the damper, in which the pre-loading regulation means are suitable for modifying the pre-loading applied to the spring in conditions of rest and the damper regulation means modify the damping capacity of the oscillations induced by the spring, wherein the control unit is operatively connected to the regulation means of the damper unit so as to vary the setting of the regulation means depending on the load signal received from the load sensor, so as to adapt the pre-loading of the spring and the damping of the damper to the load effectively weighing on the damper unit, wherein target pre-loading values of the spring and damping values of the damper are stored in the control unit depending on the load effectively weighing on the damper unit, and wherein said load sensor is a rotary sensor which measures the angle of relative rotation between the fork and the portion of the frame to which said rotary sensor is attached, said rotation being correlated to the load weighing on the damper unit.
