A frame for a motorcycle has good flexibility in a left-right direction. The frame includes left and right main frames extending from a head pipe, pivot frames extending downwardly from respective rear ends of the main frames; and a down frame extending downwardly from the head pipe below the main frames. A reinforcement frame connects the down frame and the main frames together. The frame supports an engine, and the pivot frames swingably support a swing arm thereon. The left and right main frames curve so that a gap formed between the left and right main frames in a vehicle width direction increases from the head pipe toward the rear, while a section height of each of the main frames, in a direction orthogonal to an extending direction of the main frame, decreases from the head pipe toward the rear.
