Abstract: A lower part structure of a motorcycle is provided which enables air having flowed past a radiator to be guided to transversely outer sides more efficiently. In a motorcycle, a radiator is disposed forwardly of an engine and rearwardly of a front wheel, and an air guide port opening forward is provided forwardly of the radiator. A body frame and the radiator are covered with a cowling. The cowling includes side cowls covering lateral sides of the radiator, and an undercover covering a lower portion of the body frame rearwardly of the radiator. The undercover includes a V-shaped part, and air guide surfaces extending obliquely from the V-shaped part toward transversely outer rear sides.

Abstract: A vehicle comprising a vehicle body frame (11), a front cowl (72) provided in front of the vehicle body frame, and a headlight unit (59) mounted within the width, in the vehicle's lateral direction, of the front cowl. The headlight unit has, on the opposite sides thereof, recesses (115L, 115R) recessed inward in the vehicle's lateral direction. Air intake openings (111L, 111R) for introducing air in front of the front cowl into the inner side of the front cowl are formed between the headlight unit and the front cowl.

Abstract: A side trunk mounting structure which enhances the external appearance of a two-wheeled motor vehicle. Mounting holes (113F, 113r) for mounting the side trunk (111) are formed in a rear fender (17). The side trunk mounting holes are located below a rider's seat (15).
