A motorcycle, comprising a power unit including an engine having a substantially vertically disposed cylinder and a transmission extending rearwardly from a lower part of the engine; a fuel tank arranged above the power unit; and a seat arranged behind the fuel tank; further comprising: an air cleaner unit accommodated in a space defined by a rear surface of the engine and an upper surface of the transmission; an upper part of the air cleaner unit protruding into a concave bottom surface of a rear part of the fuel tank while an outlet port of the air cleaner unit is connected to an intake port of the engine by way of a passage which is slanted downwards as it extends to the intake port of the engine. Thus, the internal volume of the air cleaner case can be increased without affecting the position of the set, the wheel base, or the width of the part of the motorcycle body which is to gripped between the knees of the rider. |
