Abstract: An engine control device capable of decreasing engine output while giving less uncomfortable feeling to the rider in the event of a failure, with a simple configuration. Engine output is decreased when a failure has been detected in a throttle valve.

The engine speed thereby can be decreased according to the preset target rotational speed. Thus, engine output can be decreased uniquely.
