Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a motorcycle capable of further increasing the capacity of a storage box while suppressing an increase of vehicle size and mounting an engine having high combustion efficiency of fuel. SOLUTION: An engine unit 30 arranged below the storage box 20 is rockable around a pivot shaft 31 with a rear wheel 55 relative to a vehicle body frame 10. To an engine body 21 of the engine unit 30, an intake pipe 36 for forming part of the main intake passage P1 to a cylinder head 23 is connected. Further, a sub-intake passage K1 branched from the main intake passage P1 is provided between first and second throttle valves 40A, 40B arranged in the intake pipe 36. In the sub-intake passage K1, the suction air in the sub-intake passage K1 is led to a space near an injector at least idling. The pivot shaft 31 is arranged below the cylinder axis L1 of a cylinder block 22 and on a front side than a crank case 24. COPYRIGHT: (C)2011,JPO&INPIT
