There is provided an intake device, in which an air cleaner is disposed behind an engine and which is configured such that air is introduced from the air cleaner to the engine through an intake passage. The intake device includes: a pressure sensor configured to detect a pressure in the intake passage; a throttle body that forms an upstream side of the intake passage; and an intake pipe that forms a downstream side of the intake passage. An attachment portion to which the pressure sensor is attached is formed on an outer peripheral surface of the intake pipe.

An all-terrain vehicle includes a frame; two seats arranged on the frame; a container arranged on the frame and located at a rear side of the seat, a top of the container being open; a power system arranged on the frame; an air filter coupled to the power system, arranged on the frame and located below the container; and a storage box arranged on the frame and located behind the two seats, the storage box being detachably coupled to the frame, the air filter and/or the power system being repairable after the storage box being removed.

There is provided a straddle-type vehicle, including: a pair of seat frames; a seat; an air cleaner; a battery; and a bracket. A rear portion of the air cleaner and the battery are positioned below the seat. The battery is disposed above the rear portion of the air cleaner. The bracket extends in a left-right direction of the straddle-type vehicle and passes between the rear portion of the air cleaner and the battery. A left end side and a right end side of the bracket are connected to the pair of seat frames respectively. The rear portion of the air cleaner is suspended by the bracket. The battery is installed on the bracket.

A position of a center of gravity of a vehicle body is easily optimized. An ABS modulator is disposed in a vicinity of a pivot bracket, which is joined to a lower rear portion of a main frame, and to which a swing arm is swingably connected.

An air intake system for a vehicle has a conduit having an internal wall forming an air passage. A deflector is disposed within the air passage. A restricting structure is disposed within the air passage between the deflector and a conduit outlet. The restricting structure defines at least in part an opening substantially laterally aligned with the deflector. The restricting structure has a lateral wall disposed downstream of the deflector and extending within the air passage. The lateral wall has a front surface generally facing a conduit inlet, and a plurality of surface-increasing features provided on the front surface. Each of the surface-increasing features has a length of at least 1 mm measured from the front surface in a direction normal thereto. An air intake system having a collector connected to the deflector and positioned to collect at least some moisture from air flowing past the deflector is also described.

There is provided an air cleaner configured to be disposed inside a vehicle body frame, the air cleaner including: an air cleaner case in which an intake chamber is formed; an intake air temperature sensor configured to detect an intake air temperature in the intake chamber; an inlet tube configured to take in air to the intake chamber; and an outlet tube configured to send out air from the intake chamber. The outlet tube has an upstream portion protruding into the intake chamber, and the upstream portion of the outlet tube has a peripheral wall formed with a through hole.

A snow bike intake, snow bike conversion kit, and/or air intake pod snow bike conversion kit, having: a throttle body coupling; an elbow-shaped intake duct coupled to the throttle body, a pre-filter body cage coupled at a rear thereof to the duct, and a textile cover fitting about the cage. The duct has an interior angle between 40 and 60 degrees. There are a plurality of flat (interior and exterior surface) sensor mounts disposed about and through the duct, including an octagonal ring of sensor mounts circumscribing the duct body. The cage has a flat front opposite the rear that has a larger diameter than a diameter of the rear. The duct has an aspect ratio of exterior angle length to diameter no greater than 3.5:1 and the duct and prefilter combined has an aspect ratio of exterior angle length to diameter no greater than 4.5:1.

There is provided an air cleaner configured to be disposed inside a vehicle body frame, the air cleaner including: an air cleaner case in which an intake chamber is formed; an air filter disposed in the intake chamber; an inlet tube configured to take in air to the intake chamber; and an outlet tube configured to send out the air from the intake chamber. The inlet tube extends in a front-rear direction. The inlet tube has a bottom wall curved downward in a side view to form a concave curved portion below a discharge port of the inlet tube. The concave curved portion is formed with a drain hole.

A snowmobile includes an engine including an engine head including a cylinder head, a supercharger, an intake manifold, throttle bodies, first joints that connect the intake manifold to the throttle bodies, second joints that connect the throttle bodies to the cylinder head, and a restrictor that connects the engine head to the first joints. The restrictor includes an engaging member that fits into grooves of the first joints, and connectors that connect the engaging member and the engine head to each other. A steering shaft is inserted between two mutually adjacent first joints which have a distance from each other greater than a distance between the other two mutually adjacent first joints.
