Abstract

To provide a straddled vehicle (1) that is able to shorten a time period until completion of engine start after an engine start instruction. An engine unit includes a single-cylinder engine (10), a compression release mechanism (D), a drive wheel (3b), a permanent magnet type motor (20), a battery (4), an inverter (61) including a plurality of switching parts (611-616), and a control device (60). The control device (60) controls the switching parts (611-616) in such a manner that, upon reception of a start instruction for starting the single-cylinder engine (10), the permanent magnet type motor (20) moves a piston (13) so as to operate the compression release mechanism (D) in a compression stroke of a first combustion cycle, and then the permanent magnet type motor (20) applies a force to the piston (13) via a crankshaft (15) such that the rotation speed of the crankshaft (15) in a second combustion cycle exceeds the pressure- reduction upper limit speed (Ld) for the compression release mechanism (D), so that the piston (13) is moved without operating the compression release mechanism (D) in a compression stroke of the second combustion cycle, thus assisting compression of the mixed gas.
