A pair of middle cowls is arranged at positions rightward and leftward of a vehicle component located at a position forward of an engine. Part of the right middle cowl is arranged at a position further forward than an air cleaner case. A space in the air cleaner case is divided by a filter element into a first space positioned at a position further downstream than the filter element and a second space positioned at a position further upstream than the filter element. The second space is smaller than the first space. The second space and a third space inward of the right middle cowl communicate with each other by a communicating portion. The second space, at least part of the third space, and an internal space of the communicating portion constitute a dirty side chamber of an air cleaner.
