Saddle riding type vehicle

A saddle riding type vehicle (1) includes a right rear arm (41R) and a left rear arm (41L) for supporting at least a pair of wheels (43) at opposite sides of a vehicle body to be movable up and down relative to the vehicle body, and a right hydraulic cylinder (71R) and a left hydraulic cylinder (71L) for operating the right rear arm and left rear arm to change a lean amount of the vehicle body. A controller (95) controls the right hydraulic cylinder and left hydraulic cylinder according to vehicle speed. Since the lean amount of the vehicle body can thereby be adjusted according to vehicle speed, both comfortable traveling performance and stability of the vehicle are ensured.
