PROBLEM TO BE SOLVED: To provide an exhaust valve actuator arrangement structure of a motor cycle which makes improvement in terms of suppression of sliding resistance between a cable and a sheath in a harness arrangement path which transmits a drive force from an actuator to an exhaust valve and inhibits width direction enlargement of a vehicle.SOLUTION: An exhaust valve actuator arrangement structure 71 of a motor cycle includes: a seat frame 15 which is provided at a rear part of a vehicle body frame 2 and extends to the rear side of a vehicle; an exhaust pipe 21 which guides an exhaust gas of a V type engine 3 mounted on the vehicle body frame 2 to the rear side of the vehicle; an exhaust valve 72 which is provided at the exhaust pipe 21 and adjusts an exhaust flow rate of the V type engine 3; an actuator 73 which is fixed to the seat frame 15 and generates an opening and closing drive force of the exhaust valve 72; a driving pulley 76 which is provided at an output shaft of the actuator 73 and has a rotation surface arranged substantially parallel to a lower edge of the seat frame 15; and a cable 77 which transmits the drive force from the driving pulley 76 to the exhaust valve 72. |
