An all-terrain vehicle has an air ventilation system positioned adjacent a rearmost point of the front ground engaging members and directing air rearwardly through an engine compartment, wherein the air ventilation system includes at least one air scoop adjacent a front of the vehicle for directing the air. In addition, an ATV is disclosed having a rear rack having an integral storage bin, where the storage bin is one piece with the rear rack. The storage bin is sealed.

A front fender is provided in front of an air-cooled engine which is a drive source of a motorcycle. An air introduction hole which opens frontward is formed at a front part of a cylinder head of the air-cooled engine. A space around a plug attachment portion for a spark plug and a space in front of the cylinder head communicate with each other through the air introduction hole. A guide portion for guiding incoming wind toward the air introduction hole is formed at a rear part of the front fender.

A three-wheeled vehicle is disclosed having a vehicle frame supported by front ground engaging members and a single rear ground engaging member. The vehicle includes an engine positioned forward of an operator area and a swing arm coupled to the single rear ground engagement member.

A straddle-type vehicle includes a fuel pipe provided on a rear side of an engine, a generator provided on the rear side of the engine and adjacent to the fuel pipe, an outside air introduction duct configured to guide air outside the straddle-type vehicle to the rear side of the engine, and a partition wall provided between the fuel pipe and the generator. The partition wall partitions a region on the rear side of the engine into a generator arrangement region where the generator is provided and a fuel pipe arrangement region where the fuel pipe is provided. The outside air introduction duct includes a first outlet configured to allow the air to flow out to the generator arrangement region.

An air scoop device having a sidewall longitudinally defined by a leading edge and a trailing edge, the sidewall extending between a top portion and a bottom portion, wherein the top portion, the bottom portion and sidewall define an interior space; an inner portion extending approximately orthogonally from a distal end of the bottom portion, wherein the inner portion further defines the interior space; the top portion having a top leading edge and a top trailing edge; a top cutout extending from the top trailing edge to a top distal end of the top portion; the bottom portion having a bottom leading edge and a bottom training edge; and bottom cutout extending from the trailing edge to the inner portion. The present invention may be configured in a kit of two air scoop devices and a set of installation instructions.

A saddle-riding vehicle includes a radiator in front of an engine of the saddle-riding vehicle and on one lateral side of the vehicle in a vehicle widthwise direction with respect to a center line in the vehicle widthwise direction. The radiator includes: a radiator body that allows coolant of the engine to flow through the radiator body; a radiator fan at a rear face of the radiator body; and a fan cover that covers the radiator fan from a rear of the radiator fan to guide exhaust air from the radiator to the one lateral side in the vehicle widthwise direction.

A straddled vehicle, including a head pipe, a main frame extending rearward from the head pipe, a fuel tank supported by the main frame, an air cleaner arranged in front of the fuel tank, a side cover formed on a lateral side of the fuel tank to partially overlap the fuel tank in a side view of the straddled vehicle, an intake port provided at an edge of the side cover and opening toward an outside of the straddled vehicle, an air cleaner chamber in which at least a part of the air cleaner is arranged, and an intake passage including a first passage between the side cover and a side surface of the fuel tank, the intake port communicating with the air cleaner chamber through the intake passage. The side cover includes a front portion located forward of the air cleaner, and the intake port is arranged rearward of the air cleaner.
