の着脱が容易に行なえる。(Effects of the invention) As detailed above, in the motorcycle of the present invention, the large load applied mainly to the head pipe and swing arm support point is absorbed by the main frame, one on each side of the left and right, with the long axis of the cross-sectional shape oriented in the vertical direction of the vehicle body. Since the body frame connected between the body frame and the swing arm support member and the engine, which is a strength member of the body frame, are supported by an integrated structural member, reinforcing members such as descending pipes as in the past are not required. There is no need for special provision and reinforcement, and the rigidity of the vehicle body frame, particularly torsional rigidity, is improved, and a highly rigid and lightweight two-wheeled vehicle body can be obtained. Furthermore, since the number of components for reinforcing the vehicle body frame can be reduced, the number of parts that are fixed to each other is reduced, the number of man-hours required for manufacturing the vehicle body frame is reduced, and the structure is simple and costs can be reduced. In addition, because the cross pipe that connects the left and right main frames to each other is placed close to the top of the engine, the engine and body frame are almost integrated, which not only makes the overall shape more compact, but also has a rectangular cross-section. Together with the main frame with its long axis pointing in the vertical direction of the vehicle body, it is possible to achieve a lightweight and highly rigid vehicle body structure. Furthermore, the engine can be attached to and removed from the cross pipe by inserting a tool between the main frames from above the vehicle body and manipulating the fasteners, so the engine can be easily attached to and removed from the vehicle body frame.
