  • Patent number: 11214139
    Abstract: There is provided a motorcycle which includes an engine including an exhaust port; an exhaust pipe connected to the exhaust port of the engine; and a catalyst disposed within the exhaust pipe. The exhaust pipe includes a catalyst case accommodating the catalyst, and a pipe connecting the exhaust port of the engine and the catalyst case. The catalyst is disposed in front of the engine. An occupied area of the catalyst in a direction orthogonal to a flow direction of exhaust gas is larger than an opening area of the pipe in a direction orthogonal to a flow direction of exhaust gas. A central axis of the catalyst is inclined with respect to a vehicle width direction in a vehicle front view. And the central axis of the catalyst and a center line of the engine in the vehicle width direction intersect at a position overlapping with the catalyst in the vehicle front view.
