A swinging arm suspension (1) is described, which is adapted to mechanically connect a front portion (11) of a three-wheeled motorcycle (10) to its rear portion (12), which comprises an articulated quadrilateral (2), comprising a pair of first lateral connecting rods (3) with the same length, a lower base segment (4) and a major base segment (5), wherein the length of the segment (4) is shorter than the length of the segment (5). At least one elastic element acts on said first lateral connecting rods (3), which first elastic element (6) is adapted to maintain, when at rest, the articulated quadrilateral (2) in a configuration in which said base segments (4, 5) are parallel to each other. The geometric lengths of said first lateral connecting rods (3) and of said segments (5) and (4) are proportionate to each other so as to ensure that the axis of symmetry of the segment (5) always traverses a constant geometric point coinciding with the lateral rotation center of the tire of the front portion (11) of the motorcycle (10) on which said suspension (1) is adapted to be installed and with respect to which said tire is adapted to rotate, thus modifying its inclination due to the effect of the action of the driver in the moment in which he has to steer.
