[0013]
On the other hand, a cushion mechanism 19 that controls the swing of the swing arm 7 is provided between the swing arm 7 and the swing arm pivot portion 14.
[0014]
The cushion mechanism 19 includes a link mechanism 20 provided between a lower end portion of the swing arm pivot portion 14 and a lower portion of the swing arm 7 in the length direction, the link mechanism 20, and the swing arm. The rear cushion 21 is interposed between the upper end of the pivot portion 14 and the rear cushion 21.
[0015]
The radiator 12 constituting the characteristic part of the present invention is disposed above the horizontally opposed engine 6 and on both sides of the vehicle body frame 2.
These radiators 12 are disposed along the front-rear direction of the vehicle body, and are fixed to the tank rail portion 15 by bolts 40 at the upper end portions thereof, and are fixed to the bracket 18 by bolts 41 at the lower end portions thereof. Thus, the vehicle body frame 2 is mounted.
In addition, these radiators 12 are provided with an electric fan 22 for forcibly guiding cooling air to the radiator 12. By sucking air that has entered the inside of the vehicle body from the front of the vehicle body, the air is absorbed. Then, after passing through each radiator 12, it is discharged to the side of the vehicle body.
[0016]
Further, a number of exhaust pipes 23 are connected to the lower part of the horizontally opposed engine 6.
Conventionally, these exhaust pipes 23 are connected to a cylinder head 24 via a mount 25 attached in a substantially horizontal state, as shown in FIG. In this embodiment, the mount 26 is directed toward the inside of the vehicle body with respect to the cylinder head 24. The exhaust pipe 23 is connected via the inclined mount 26.
