A motorcycle comprising: a driving source configured to output a torque that drives a drive wheel ; an accelerator grip that is operated by a rider and is rotatable at least between a first rotation position (α1) and a second rotation position (α2) in an opening direction (A1) that is a rotation direction from the first rotation position (α1) to the second rotation position (α2) and in a closing direction (A2) that is a rotation direction from the second rotation position (α2) to the first rotation position (α1); an energizing member configured to energize the accelerator grip toward the first rotation position (α1); an accelerator detector configured to detect a rotation position of the accelerator grip ; a vehicle speed detector configured to detect vehicle speed; a driving source controller configured to control the driving source , based on the rotation position of the accelerator grip , such that, when the rotation position of the accelerator grip is the first rotation position (α1), the output torque of the driving source is minimum and, when the rotation position of the accelerator grip is the second rotation position (a2), the output torque of the driving source is maximum; and a speed limiter configured to limit the output torque of the driving source such that the vehicle speed does not exceed an upper limit; and a speed limiter stopping device configured to turn off the speed limiter , based on the rotation position of the accelerator grip ; characterized in that the accelerator grip is configured to be rotatable farther in the closing direction (A2) than the first rotation position (α1), and the speed limiter stopping device is configured to turn off the speed limiter when the rotation position of the accelerator grip becomes a predetermined rotation position (α3) located farther in the closing direction (A2) than the first rotation position (α1). a driving source configured to output a torque that drives a drive wheel ; an accelerator grip that is operated by a rider and is rotatable at least between a first rotation position (α1) and a second rotation position (α2) in an opening direction (A1) that is a rotation direction from the first rotation position (α1) to the second rotation position (α2) and in a closing direction (A2) that is a rotation direction from the second rotation position (α2) to the first rotation position (α1); an energizing member configured to energize the accelerator grip toward the first rotation position (α1); an accelerator detector configured to detect a rotation position of the accelerator grip ; a vehicle speed detector configured to detect vehicle speed; a driving source controller configured to control the driving source , based on the rotation position of the accelerator grip , such that, when the rotation position of the accelerator grip is the first rotation position (α1), the output torque of the driving source is minimum and, when the rotation position of the accelerator grip is the second rotation position (a2), the output torque of the driving source is maximum; and a speed limiter configured to limit the output torque of the driving source such that the vehicle speed does not exceed an upper limit; and a speed limiter stopping device configured to turn off the speed limiter , based on the rotation position of the accelerator grip ; characterized in that the accelerator grip is configured to be rotatable farther in the closing direction (A2) than the first rotation position (α1), and the speed limiter stopping device is configured to turn off the speed limiter when the rotation position of the accelerator grip becomes a predetermined rotation position (α3) located farther in the closing direction (A2) than the first rotation position (α1). <EOS>
