Abstract: A vehicle, such as a motorcycle, can facilitate maintenance of an air cleaner without complicating a peripheral structure of a fuel tank. The vehicle can include a body frame, a rear arm attached to the body frame to support a rear wheel, a rear cushioning member provided between the body frame and the rear arm, and an engine fixed to the body frame. The vehicle can further include a fuel tank supported rotatably at a supporter arranged closer to a rear side of the vehicle than a substantially central position of an axis of the rear cushioning member.

Abstract: A motorcycle can include an engine, a fuel tank, a seat, and a canister. The fuel tank can have an upper surface and an inclined surface arranged to extend obliquely downward from a rear end of the upper surface toward a back of the motorcycle. The seat can include a seat front portion and a seat rear portion. The seat front portion can be provided on the inclined surface, and the seat rear portion can extend toward the back of the motorcycle. The canister can be arranged between the inclined surface and the seat front portion. The canister can store fuel gas generated in the fuel tank, and supply the fuel gas to the engine. At least one of the inclined surface and the lower surface can have a first cavity that stores the canister.

Abstract: A motorcycle that securely prevents adhesion of fuel to an external surface of a fuel tank as it is bounced back in the course of refueling, and avoids interference with parts positioned below the fuel tank. The fuel tank has a filler opening formed in its transversal center with an upward opening. A projecting part projecting toward the filler opening is provided on a bottom wall of the fuel tank opposite to the filler opening.

Abstract: A fuel pump for a vehicle is resistant to damage and effectively uses fuel in a fuel tank. The fuel tank is saddle-shaped and straddles an upper side frame section of the vehicle. A left side tank section extends downward on a left side of the upper side frame section and a right side tank section extends downward on a right side. A fuel pump in the interior of the fuel tank is fixed on the bottom surface of either the left or right side tank section. For off-road saddle-riding type vehicles, the fuel pump is provided anterior to a fuel tank central portion when viewed from a side of the vehicle to ensure easy handling and foot landing properties.

Abstract: A fuel supply device for a motorcycle facilitates a narrower vehicle width to improve maneuverability. A fuel tank is disposed above a body frame, and a first fuel pump is fixed to a part of the fuel tank facing the body frame and positioned inside of the fuel tank via a mount seat. The first fuel pump is disposed such that at least a portion of the mount seat overlaps the vehicle body frame as viewed from above the motorcycle.

Abstract: A vehicle, such as a motorcycle, includes a fuel tank and a fuel pump mounting arrangement that inhibits or prevents fuel from leaking from the fuel tank. The fuel pump mounting arrangement includes a mount assembly that secures the fuel pump within the fuel tank. At least a portion of the fuel pump mount assembly is embedded in a wall portion of the fuel tank, and includes a plate and a plurality of nuts fixed to the plate.

Abstract: A wheeled vehicle includes a body frame. At least one wheel can contact with the ground. A coupling device rotatably couples the wheel with the body frame. A handlebar extends from a portion of the coupling device. At least a portion of the handlebar located adjacent to the portion of the coupling device has a first geometrical moment of inertia and a second geometrical moment of inertia. The first geometrical moment of inertia is defined about a first neutral axis that extends generally parallel to an impact load transferring axis along which an impact load from the ground transfers to the handlebar. The second geometrical moment of inertia is defined about a second neutral axis that intersects the first neutral axis generally at right angles. The second geometrical moment of inertia is smaller than the first geometrical moment of inertia.
