Abstract: A vehicle, such as a straddle-type vehicle, can include an engine, a catalyst and an air cleaner. The catalyst can be disposed in an expansion chamber of the vehicle. At least a part of the air cleaner can be disposed above a swing arm of the vehicle, and at least a part of the expansion chamber can be disposed below the swing arm. The air cleaner can further be disposed to the rear of a shock absorber of the vehicle. Thus, the influence of heat from the catalyst and the engine on the air cleaner can be reduced. Consequently, efficiency of air induction into the engine can be increased, thereby improving engine output.
