A motorcycle includes an internal combustion engine, a frame, a fuel tank for carrying a fuel to be consumed by the internal combustion engine, and a container connected to the internal combustion engine and the fuel tank. The container is configured to store fuel evaporating from the fuel tank, and the container in a position of use is at least partially covered by the fuel tank. The fuel tank is supported pivotably relative to the frame between a maintenance position and the position of use.

A fuel cell two-wheeled vehicle includes an electric machine configured to drive a drive wheel, an air-cooled fuel cell configured to supply electric power to the electric machine, and a fuel gas tank that accumulates fuel gas supplied to the fuel cell. A battery pack is disposed in a space between an intake air inlet and an air intake duct and surrounded by a seat and a vehicle body cover. The intake air inlet is disposed below a front portion of the seat.

An air-cleaner structure of a saddle-ride vehicle is provided with an air-cleaner case arranged between a seat and a head pipe located in front of the seat. The air-cleaner case is provided with a bottom half and a top half. The bottom half is arranged in a space surrounded by a rear face of the head pipe and a pair of left and right main frames extending from the head pipe toward the rear of the vehicle. The top half is situated above the main frames. The top half is provided in a vertical two division structure. A dividing surface of the vertical two division structure of the top half is inclined in the vehicle-longitudinal direction. An air-cleaner element is mounted along the inclined dividing surface.

A straddle-type vehicle (100) includes a frame (20) and an engine (10) mounted on the frame (20), the engine (10) includes a cylinder head (11) positioned toward the rear end of the frame, and located below a saddle seat (80). The cylinder head laces toward the rear end of the frame, which allows the heated cylinder head of the engine and the exhaust pipe connected to the cylinder head to avoid contact with the vehicle the user's legs while riding the vehicle, so the effect of heat emitted from the cylinder head on the rider's experience is reduced.

A straddled vehicle including a body frame having a head pipe, a front cover in front of the head pipe, an exterior cover laterally covering the body frame, a fuel tank disposed behind the head pipe, an air cleaner disposed directly below the fuel tank, a duct disposed between the front cover and the head pipe and extending from an opening in the front cover, and a wind guide cover disposed between the head pipe and the fuel tank. The fuel tank and the exterior cover forms a wind guide pathway therebetween, the wind guide pathway being directly below the fuel tank, and being laterally covered with the exterior cover. The wind guide cover is configured to lead traveling wind passing through the duct from the opening to the wind guide pathway, so that the wind guide pathway leads the traveling wind to an air intake port of the air cleaner.
