摘要:
A frame of a motorcycle includes a head pipe configured to support a steering shaft, a first frame configured to extend from the head pipe, through above and rearward of an engine, and to rearward of a vehicle body, a second frame that is located under the first frame and configured to extend from the head pipe, through forward and downward of the engine, and to rearward of the vehicle body, a bracket by which a first component is mounted to the second frame, and a coupling member that is mounted to the second frame to couple a second component to the second frame, and the bracket is integral with the coupling member. An engine bracket of a motorcycle is manufactured by forging such that a region subjected to tensile stress is made thicker than a region in the vicinity of the region which is subjected to the tensile stress.
