PROBLEM To provide a straddled vehicle that is able to shorten a time period until completion of engine start after an engine start instruction. SOLUTION An engine unit includes a single-cylinder engine, a compression release mechanism, a drive wheel, a permanent magnet type motor, a battery, an inverter including a plurality of switching parts, and a control device. The control device controls the switching parts in such a manner that, upon reception of a start instruction for starting the single-cylinder engine, the permanent magnet type motor moves a piston so as to operate the compression release mechanism in a compression stroke of a first combustion cycle, and then the permanent magnet type motor applies a force to the piston via a crankshaft such that the rotation speed of the crankshaft in a second combustion cycle exceeds the pressure-reduction upper limit speed for the compression release mechanism, so that the piston is moved without operating the compression release mechanism in a compression stroke of the second combustion cycle, thus assisting compression of the mixed gas.
