As shown in FIG. 6, a reserve tank 69, a regulator 70, etc. are provided inside the side cowls 46L, 46R. Components can be stored, and the degree of freedom of component placement is improved.

  Further, since most of the rear end region BE of the upper portion UP is not covered with the side cowl 46 and is exposed to the outside, it is possible to suppress an undesirably large size of the side cowl 46 in the front-rear direction. In addition, it is possible to confirm the attachment / detachment of the side cowl 46 from the exposed part of the rear part of the cylinder block 26, and the maintainability is improved. Specifically, the locking pin 96 of the right side cowl 46R in FIG. 8 is aligned with the through hole 80a of the first mounting portion 80 of the reserve tank 69 in FIG. 3, and the left side cowl 46L in FIG. 4 and the through hole 84a of the third mounting portion 84 of the cowl bracket 82 of FIG.

  As shown in FIG. 5, since the reserve tank 69, the regulator 70, and the harness 82, which are peripheral devices necessary for driving the engine, are arranged between the side cowls 46L, 46R and the engine E, the side cowl 46L , 46R can protect these peripheral devices 69, 70, 82 and prevent the peripheral devices 69, 70, 82 from being exposed to the outside of the vehicle body, thereby improving the aesthetics of the motorcycle.

  As shown in FIG. 1, since the reserve tank 69 is disposed on the side of the cylinder block 26, the center of gravity of the motorcycle is lowered as compared with the conventional case where the reserve tank 69 is disposed on the front upper side of the engine.

  Further, since the side cowl 46 and the lower cowl 56 are integrally connected, the entire surface area of the cowl is increased, and a further volume feeling is obtained. In addition, since the cowl assembly ASSY can be assembled to the vehicle body in a state where the side cowl 46 and the lower cowl 56 are assembled into the cowl assembly ASSY, the assemblability is improved.

  The present invention is not limited to the above-described embodiment, and various additions, modifications, or deletions can be made without departing from the gist of the present invention. For example, in the above-described embodiment, the side cowl 46 is formed in an N shape, but it is sufficient that at least a part of the cylinder block 26 is covered from the outside, and a shape other than the N shape, for example, an L shape, It may be formed in an I shape or an arc shape. Further, a part of the front end region FE of the upper part UP of the engine E may be exposed from the side cowl 46. Furthermore, in the above-described embodiment, almost the entire rear end region BE of the upper part UP is exposed, but it is only necessary that a part of the rear end region BE is exposed.

  Further, an engine control unit (ECU), which is a kind of peripheral device necessary for driving the engine E, a canister for reducing vaporized gas, etc. may be arranged inside the side cowl 46, or the engine In addition to peripheral devices necessary for driving E, for example, an engine cover for noise prevention, an anti-theft device, an ABS unit, an antenna for wireless communication, and the like can be arranged. Further, the engine E mounted on the motorcycle of the present invention preferably has three cylinders or less, and may have only one cylinder, and preferably has a vehicle width direction dimension and a vertical dimension that are relatively small. Therefore, such a thing is also included in the scope of the present invention.
