Abstract
A straddled vehicle includes a gear position sensor abnormality detector which is configured to detect an abnormality of a gear position sensor which is provided at a crankshaft-supporter-integrated transmission supporter. The gear position sensor abnormality detector determines that the gear position sensor has an abnormality when the shift of a straddled vehicle from a stopped state to a running state is detected based on a signal from a rotation speed sensor while the gear position detected by the gear position sensor is included in a high-speed gear position class. Furthermore, the gear position sensor abnormality detector determines that the gear position sensor has an abnormality when the gear position detected by the gear position sensor is included in a low-speed gear position class and is different from a gear position estimated based on a signal from a crankshaft sensor and a signal from the rotation speed sensor.
