A rear end exhaust portion of an exhaust system connected to a cylinder head provided on an engine body carried on the vehicle body frame forwardly of the rear wheel is disposed at a position higher than the axle. An exhaust control valve for adjusting the flow area in an exhaust pipe, which forms part of the exhaust system, is disposed in the exhaust pipe. The exhaust control valve is disposed forwardly and upwardly of the axle of the rear wheel to dispose the exhaust control valve in a better environment.
