A riding-saddle motor vehicle (4) comprising a front frame (8) which extends along a longitudinal direction (Y-Y) having at least one front wheel (12), a rear frame (14) having a pair of rear wheels (16, 20) mounted on opposite sides of a rear wheel axis (22), a motor unit (24) mounted on board said front frame (8) and adapted to provide a driving torque to said pair of rear wheels (16, 20) and/or said front wheel (12). Said motor unit (24) is connected to said rear wheel axis (22) by means of an articulated transmission joint (32) adapted to allow a relative rotation, around said longitudinal direction (Y-Y), between said front frame (8) and said rear frame (14), and transmit a driving torque to said pair of rear wheels (16, 20).
骑鞍式机动车辆(4)包括:沿着纵向方向(Y‑Y)延伸的具有至少一个前轮(12)的前框架(8);具有安装在后轮轴线(22)的相反的侧部上的成对的后轮(16、20)的后框架(14);安装在所述前框架(8)的板上并且适于向所述成对的后轮(16、20)和/或所述前轮(12)提供驱动扭矩的马达单元(24)。所述马达单元(24)借助于铰接式传动接合部(32)而连接至所述后轮轮轴(22),该铰接传动接合部适于:允许在所述前框架(8)与所述后框架(14)之间绕所述纵向方向(Y‑Y)的相对旋转,以及向所述成对的后轮(16、20)传递驱动扭矩。
