The rear of a motorcycle (4) with cardan suspension comprising a rear frame (12), a fork (16), hinged to said frame about a hinging axis (X-X), the fork rotatably supporting the rotation pin (20) of a rear wheel (24) of the motorcycle around a rotation axis (Y-Y), the fork supporting a cardan-shaft transmission comprising at least one first transmission shaft (28), suitable to be connected to a power take-off (PTO) of an associable engine, at least one final shaft (32) provided with a pinion (36) rotatably connected to said rear wheel, wherein between the first transmission shaft and the final shape is interposed a first cardan joint (40), a floating arm (48) that supports said pinion of the final shaft, the arm being floating around said rotation axis (Y-Y) of the rear wheel. The floating arm comprises a cup portion (52) arranged coaxially to the rotation pin and having at least an inner end (56) that houses and supports said pinion, and an outer appendix (60) arranged cantilevered with respect to the cup portion, wherein the cup portion is released rotatably by the rotation pin of the wheel, wherein the appendix is mechanically connected to the frame through the interposition of a hinged reaction rod (64), in correspondence of opposite axial ends (68, 70), at the frame and at the appendix respectively. Advantageously, the fork comprises a front cover panel (26), arranged at least partially coaxially to the rotation pin on the side opposite to a centreline plane (M-M) of the associable rear wheel, wherein the outer appendix comprises a first section (72) that protrudes with respect to the cup in the axial direction, parallel to said rotation axis so as to project axially from said cover panel, and a second section (76) that comprises a portion recessed axially towards a centreline plane of the associable rear wheel.
