The body frame includes right and left frame members (tank rails)(3, 3) disposed on the lateral one and the other sides, a cross member (50) connecting the right and left frame members to each other, and a bracket (53) formed integrally with the cross member. The cylinder part (cylinder head)(24) of the engine is directly connected to the bracket.
