A 
fuel tank is disposed under a flat footboard. A vehicle body cover is disposed laterally of the 
fuel tank. An opening introduces travelling wind to a space between the 
fuel tank and the vehicle body cover. A first 
exhaust pipe is located upstream of a catalyst and is connected to an exhaust port. A catalyst housing portion accommodates the catalyst, is connected to the first 
exhaust pipe, and extends backwardly from the first 
exhaust pipe. A second exhaust 
pipe is located downstream of the catalyst, is connected to the catalyst housing portion, extends backwardly from the catalyst housing portion, and is connected to a silencer. The first exhaust 
pipe at least partially overlaps with the fuel tank in a vehicle front view. The catalyst housing portion is at least partially disposed rearward of the space between the fuel tank and the vehicle body cover.
