。Conventionally, this type of device includes an engine and a turbocharger having an exhaust turbine inserted in the exhaust passage of the engine, located in the middle part of a vehicle body having front and rear wheels, and located downstream of the turbine in the exhaust passage. A type equipped with a catalyst for purifying exhaust gas is known, but in this case, the amount of exhaust gas guided to the downstream side of the exhaust passage increases due to the supercharging action of the turbocharger, and accordingly, the amount of exhaust gas guided to the downstream side of the exhaust passage increases to some extent. The catalyst needs to be more or less large, and the increased size of the two-wheeled vehicle has the disadvantage of impairing its driving performance. In other words, a relatively large catalyst is relatively heavy, and it is difficult to place it on the central axis of the vehicle body due to space constraints, so it is difficult to place it on the central axis of the vehicle body. When placed on the other side, there are disadvantages such as loss of weight balance and reduction of left and right bank angles.

The exhaust passage (4) on the downstream side is formed into at least two left and right branch passages (4b) (4b), and the catalyst (7)
Prepare at least two on the left and right, and place one on each side in the corresponding passageway (
4b), thus making it possible for the catalyst (7) to be obtained as a whole in a relatively large size. To explain further, 2
The book branch passage (4b) (4b) is distributed to the left and right with respect to the central axis XX of the vehicle body (1). extending rearward in close proximity and having each catalyst (7) provided thereon;
In this way, the weight balance is not impaired and the left and right bank angles are not reduced.

The catalyst (7) is also activated, and exhaust gas purification is performed by both catalysts (71f71).

0) According to the present invention, the downstream side of the exhaust passage is branched into at least two left and right branch passages, and each passage is provided with each catalyst. The catalyst is relatively large as a whole and can cope well with relatively heavy exhaust gas, and in this case, it is preferable to arrange the two branch passages to the left and right with respect to the central axis of the vehicle body. According to this, the weight balance of the vehicle body is not impaired, and the left and right bank angles are not decreased, so that driving performance is not impaired.
