ABSTRACT:
The invention prevents a decrease in a bank angle while cornering and reduces damage incurred to an AMT mechanism when tumbling over. A motorcycle1includes a cylinder block47of an engine, a crankcase49located below this cylinder block47, a transmission55located behind this crankcase49and provided with a multistage shifting mechanism having multistage change gears, a clutch for connecting/disconnecting transmission of rotation when shifting the change gears of this transmission55, and an AMT mechanism63for automatically actuating this clutch and shifting the change gears of the transmission55. Since this AMT mechanism63is located behind the cylinder block47and above the transmission55, a decrease in the bank angle is prevented while cornering, and fatal damage to the AMT mechanism63can be reduced when the motorcycle1tumbles over.
