Motorcycle

In a vehicle body frame (1) including a front frame portion (3) extending rearward from a head pipe (2), and a rear frame portion (5) extending downward or rearward from a rear end of the front frame portion (3), a forward portion of the rear frame portion (5), for example, a lumber frame (5), includes a reduced-width portion overlapping with a vehicle body center line extending in a forward and rearward direction when viewed from above, and having a shape in which a width in a rightward and leftward direction is smaller than a length in an upward and downward direction. Devices incorporated into the motorcycle, such as a canister, a battery, an ABS unit, and a suspension unit, are laid out in spaces lateral relative to the reduced-width portion.
