<p>An air intake system employed in a motorcycle for supplying combustion air to a motor engine includes a head tube (5) and a head block (4) which is formed with the head tube (5) to define left and right communicating ducts (46, 47) therebetween. The head block (4) has forward and rearward end walls (43, 45) which cooperate with the head tube (5) to define front and rear passageways (48, 49). The forward end wall (43) has first and second intake ports (431, 432) configured to permit air scooped through one of the intake ports (431, 432) to blow rearwardly. An air flow directing unit (6) is disposed in the front passageway (43) to permit air scooped through one of the intake ports (431, 432) to flow only through a corresponding one of the left and right communicating ducts (46, 47). The other one of the first and second intake ports (431, 432) and a corresponding one of the left and right communicating ducts (46, 47) are adapted for accommodating wiring of the motorcycle.</p> |
