An all terrain vehicle has a frame assembly. A pair of front wheels and a pair of rear wheels support the frame assembly. A front fender assembly extends over at least a portion of the front wheels. An engine is disposed between the front wheels and the rear wheels. The engine is water-cooled using a radiator and fan combination that is positioned forward of the engine. A belt drive forms a portion of a transmission that transfers power from the engine to at least the rear wheels. The belt drive is air cooled with air that is pulled into the belt drive by fans positioned within a belt case. The air is drawn from an air chamber formed within the front fender assembly. The chamber is positioned vertically higher than the radiator and fan combination and rearward thereof. The air passes between the chamber and the belt case through a duct. The duct extends downward and incorporates a central trap portion. The duct is positioned to lie at least partially within an area that overlaps the fan from a front elevation view. The duct also bends across a central longitudinal plane from inlet to outlet to allow a compact configuration while positioning the duct in protected regions.
