A fuel tank of a motorcycle is disposed between a head pipe and a rider's seat. A cylindrical body forming a filler port is disposed at an upper portion of a tank main body of the fuel tank. A first mounting portion is formed on an outer peripheral surface of the cylindrical body projecting from the upper portion of the tank main body. A tank upper portion cover is mounted on the first mounting portion so as to cover an upper portion of the fuel tank.

A straddle vehicle comprises a first external member having an outer surface exposed to outside of the straddle vehicle, the first external member includes a base section and a coating section coated on the base section, the coating section includes a color layer, and a light transmission layer stacked on the color layer and having the outer surface exposed to outside of the straddle vehicle, and the light transmission layer includes a self-restoring resin.

In an off road vehicle having a cradle type vehicle body frame, an electrical component is arranged forwardly of rider's legs. A vehicle body frame includes a head pipe, a main frame, a pivot frame, a down frame and a lower frame so as to be formed in a cradle of a closed loop shape in a side view. An engine is supported inside the cradle, and a fuel tank is arranged above the cradle. A vehicle body cover for covering the engine and the fuel tank includes a tank shroud, a side cover and an under cover. A portion of the side cover swells laterally and has an apex located within the cradle on the lateral side of a cylinder section. A fuel pump or an ABS unit as a heavy electrical component is arranged on the inside of the apex.

A motorcycle with a power unit for reducing the running resistance of a flow of air by effectively straightening the flow of air while ensuring the visibility of a tail light unit. The tail light unit emits light toward the rear of the vehicle and is arranged in a rear cowl which covers a rear part of the body frame at least behind an operator's seat. A straightening plate covers a rear part of a body frame F from below while allowing air flowing from a power unit to the rear to be straightened and discharged to the rear of the vehicle. The straightening plate is fixedly arranged below a rear cowl, which covers the rear part of the body frame from the side and above, behind an operator's seat.

A saddle-riding vehicle include a body frame, an engine which is supported on the body frame, an exhaust pipe which extends rearward from a front portion of the engine 41, a fuel tank which is disposed on a side of the engine 41, a skid guard which covers the engine and the exhaust pipe from fronts thereof, and a side guard which covers a side portion of the fuel tank. The skid guard and the side guard are disposed to have an overlap portion where the skid guard and the side guard overlap partially. Therefore, the saddle-riding vehicle prevents mud or stone from entering an inside of a guard member, and prevents a fuel tank from being exposed through a gap to eliminate a deterioration of an external design of the saddle-riding vehicle.

Lateral sides of an engine and a fuel tank are covered with a tank cowling formed by connecting a front cowling and a rear cowling. The front cowling is provided with a flange in which a through hole is formed. The long sides of the through hole are formed in parallel with a cylinder axis of a cylinder section. A gate provided on a lower connecting edge portion of the rear cowling with which the flange overlaps is inserted into the through hole and connected by the clip. The front cowling and the rear cowling are fastened through a bolt on a vehicle body side above and below the connecting section by the clip. With this structure, the force applied to the connecting section is reduced and the connecting section is decreased in size.

A straddle-type vehicle capable of restricting input of a load from a fastening member, which joins multiple tank covers to each other, to the surface of a fuel tank. A fastening member designed to join a first tank cover and a second tank cover together is disposed to face the surface of a fuel tank and at least one of the first tank cover. The second tank cover has a convex portion facing the surface of the fuel tank at a position near the fastening member.
