Abstract

Provided is a motorcycle provided with a front fender (34) which can effectively cool an engine (19) by an aerodynamic air flow. The front fender (34) is provided with right and left bulged portions (36, 36) which protrude laterally with respect to the vehicle body in a position in front of front forks (24). Besides accommodation portions (77) for accommodating the front forks, right and left recesses (78, 78) which are recessed in a central direction of the vehicle width are provided in positions at the rear of the bulged portions and in front of the front forks. A part of the aerodynamic air flow is swirled (85) in the recesses. Due to the swirl, the recesses have a negative pressure lower than the surroundings, so that the aerodynamic air flow is drawn toward the center of the vehicle width.

Description

technical field [0001] The present invention relates to a motorcycle with a front fender on the front wheel. Background technique [0002] In order to prevent the front wheels from splashing mud and the like, the two-wheeled motor vehicle is provided with front fenders on the front wheels. Conventionally, there has been proposed a technique in which a front fender has functions other than the mud-splash function by cleverly designing its shape (for example, refer to Patent Document 1). [0003] The front fender disclosed in Patent Document 1 is composed of a front portion located on the front side of the front fork and a rear portion extending rearward from the front portion. [0004] The width of the rear side portion in the vehicle width direction is smaller than the inner width between the front forks. On the other hand, the width of the front side portion in the vehicle width direction increases toward the rear, and the maximum width is close to the outer width between...
