Provided is a motorcycle which can provide a space inside a main frame to place other members therein, and make it difficult for an outside impact to be transmitted to a hydraulic unit. A motorcycle comprises a head pipe which supports a rotary shaft around which a handle is rotatable with respect to a vehicle body; a pair of right and left main frames extending in a forward and rearward direction from the head pipe; and a hydraulic unit mounted to one of the pair of right and left main frames, wherein the pair of right and left main frames have increased-space portions, which define a space with a dimension increasing in an obliquely rearward direction from the head pipe toward maximum-space portions of the main frames, and wherein the hydraulic unit is mounted to an outer portion of the increased-space portion of one of the main frames.
