A motorcycle comprising: a pair of seat frames extending in a front/rear direction and spaced apart from each other by an interval in a width direction of the motorcycle; a rear wheel (Wr) disposed below the pair of seat frames in a side view of the motorcycle; a rear fender including a first fender portion disposed above the rear wheel (Wr) and a second fender portion extending downward from a rear end portion of the first fender portion to behind the rear wheel (Wr), the first fender portion being mounted on the pair of seat frames; a cross member disposed above the rear fender and coupling the pair of seat frames; a mounting member extending from the rear fender and including a pair of light mounting portions that are spaced apart from each other by an interval in the width direction of the motorcycle; and a taillight disposed above the rear fender and mounted on the pair of light mounting portions, characterized in that said mounting member extends higher than the cross member and having a length in the width direction of the motorcycle greater than a length in a front/rear direction of the motorcycle such that the mounting member deflects readily in the front/rear direction to absorb the front/rear direction vibrations transmitted from the rear fender; and a length of each light mounting portion in the width direction of the motorcycle is greater than a length of the light mounting portion in the front/rear direction of the motorcycle, and a coupling member couples the pair of light mounting portions and a length of the coupling member in the width direction of the motorcycle is greater than a length of the coupling member in the front/rear direction of the motorcycle, or a space is provided between the pair of light mounting portions without a coupling member. a pair of seat frames extending in a front/rear direction and spaced apart from each other by an interval in a width direction of the motorcycle; a rear wheel (Wr) disposed below the pair of seat frames in a side view of the motorcycle; a rear fender including a first fender portion disposed above the rear wheel (Wr) and a second fender portion extending downward from a rear end portion of the first fender portion to behind the rear wheel (Wr), the first fender portion being mounted on the pair of seat frames; a cross member disposed above the rear fender and coupling the pair of seat frames; a mounting member extending from the rear fender and including a pair of light mounting portions that are spaced apart from each other by an interval in the width direction of the motorcycle; and a taillight disposed above the rear fender and mounted on the pair of light mounting portions, characterized in that said mounting member extends higher than the cross member and having a length in the width direction of the motorcycle greater than a length in a front/rear direction of the motorcycle such that the mounting member deflects readily in the front/rear direction to absorb the front/rear direction vibrations transmitted from the rear fender; and a length of each light mounting portion in the width direction of the motorcycle is greater than a length of the light mounting portion in the front/rear direction of the motorcycle, and a coupling member couples the pair of light mounting portions and a length of the coupling member in the width direction of the motorcycle is greater than a length of the coupling member in the front/rear direction of the motorcycle, or a space is provided between the pair of light mounting portions without a coupling member.
