Abstract:
1. A motorcycle configured to be propelled by a friction between a drive wheel thereof and a ground surface with which the drive wheel is in contact; comprising: a power unit configured to drive the drive wheel, the drive wheel being a rear wheel; a speed control device configured to control drive of the drive wheel; a controller configured to control the speed control device to increase a rotational speed of the drive wheel while maintaining a state in which the drive wheel does not slip on the ground surface in a predetermined amount or more of slip; a power unit rotational speed sensor unit configured to detect a rotational speed of the power unit; a non-drive wheel rotatably mounted separately from the drive wheel; and a non-drive wheel rotational speed sensor unit configured to detect a rotational speed of the non-drive wheel; wherein the controller is configured to control the speed control device to increase the rotational speed of the drive wheel while maintaining a state in which the drive wheel does not slip on the ground surface in the predetermined amount or more, when the rotational speed of the power unit is not smaller than a predetermined value and when a value of data indicating the rotational speed of the non-drive wheel that is detected by the non-drive wheel rotational speed sensor unit is less than a predetermined value.
