<p>The invention increases the capacity of an engine intake system and the capacity of a housing box without raising a height of a seat. To achieve this, in a motorcycle (10), a crank case (52), an engine (16) extending a cylinder (54) forward from the crank case (52), and a housing box (21) are arranged under a seat (22). An intake passage (98) is extended rearward from the above of the cylinder (54), an intake port (96a) of the intake passage (98) is connected to an air chamber (47), and an intake port (47a) of the air chamber (47) is connected to an air cleaner (45) through a communication path (46). The air chamber (47) is arranged upward of the crank case (52). The housing box (21) is arranged rearward of the air chamber (47). The air cleaner (45) is arranged sideways of the housing box (21). <IMAGE></p> |
