Abstract

The overall surface of the upper-cowl body and the headlamp cover attached to the front part thereof are formed with a streamlined, basic cross-sectional shape such as an arc, parabola or some analogous section, which curves with its tangent being gradually directed toward the rear, from the forward part to the rear outer sides. A pair of air intakes opening forward for guiding air for engine supercharging, cooling heat exchanger, etc., are provided on the outer sides of the headlamp cover while a pair of turn signal lenses are arranged on the outer sides of the openings of the air intakes, so that the lens surfaces are projected forward from the basic cross-sectional shape. Air flowing sidewards and rearward along basic cross-sectional shape is guided along the turn signal lens surfaces into the air intakes.
