An exhaust pipe is branched into a right side connecting portion and a connecting portion. The right side connecting portion is connected to a first muffler while the connecting portion is connected to a second muffler through a space under a boundary between a driver's seat and a passenger's seat. It is possible to eliminate the need for reducing the thickness of a portion, corresponding to each of the driver's seat and the passenger's seat, of a cushioning material of the seat and to ensure a sufficient range of vertical movement of a rear wheel. The aforementioned arrangement permits the weight of the exhaust system to be reduced without sacrificing the cushioning characteristic of the seat and the range of vertical movement of the rear wheel.
