A straddled vehicle comprising: a vehicle body including a head tube and a frame, the frame extending backward from the head tube in a top view, the frame being disposed so as to be shifted in the left-right direction from a left-right center line, the left-right center line extending in the forward-backward direction while passing through the head tube; a front fork supported by the head tube; a multi-stage transmission including plural gears; an actuator mechanism for changing a gear of the multi-stage transmission, the actuator mechanism including a clutch motor and/or a shift motor, the clutch motor being disposed further in the backward direction than the head tube, the shift motor being disposed further in the backward direction than the head tube; a motor control unit configured to control the clutch motor and/or the shift motor; an electric cable connecting the motor control unit to the clutch motor and/or the shift motor; and a main harness bundling an intermediate section of the electric cable together with another electric cable, the motor control unit being attached to the frame, which holds the main harness, such that a distance in the left-right direction from the left-right center line to the motor control unit is longer than a distance in the left-right direction from the left-right center line to a motor control unit branch portion, the motor control unit branch portion being a portion where an end portion of the electric cable connected to the motor control unit branches from the main harness, and at least a part of the motor control unit is positioned further in the backward direction than the front fork and further in the forward direction than the clutch motor and/or the shift motor. a vehicle body including a head tube and a frame, the frame extending backward from the head tube in a top view, the frame being disposed so as to be shifted in the left-right direction from a left-right center line, the left-right center line extending in the forward-backward direction while passing through the head tube; a front fork supported by the head tube; a multi-stage transmission including plural gears; an actuator mechanism for changing a gear of the multi-stage transmission, the actuator mechanism including a clutch motor and/or a shift motor, the clutch motor being disposed further in the backward direction than the head tube, the shift motor being disposed further in the backward direction than the head tube; a motor control unit configured to control the clutch motor and/or the shift motor; an electric cable connecting the motor control unit to the clutch motor and/or the shift motor; and a main harness bundling an intermediate section of the electric cable together with another electric cable, the motor control unit being attached to the frame, which holds the main harness, such that a distance in the left-right direction from the left-right center line to the motor control unit is longer than a distance in the left-right direction from the left-right center line to a motor control unit branch portion, the motor control unit branch portion being a portion where an end portion of the electric cable connected to the motor control unit branches from the main harness, and at least a part of the motor control unit is positioned further in the backward direction than the front fork and further in the forward direction than the clutch motor and/or the shift motor. a distance in the left-right direction from the left-right center line to the motor control unit is longer than a distance in the left-right direction from the left-right center line to a motor control unit branch portion, the motor control unit branch portion being a portion where an end portion of the electric cable connected to the motor control unit branches from the main harness, and at least a part of the motor control unit is positioned further in the backward direction than the front fork and further in the forward direction than the clutch motor and/or the shift motor.
