Referring to fig. 1 and 2, the present application discloses a vehicle, which may be a riding vehicle 10 or an all-terrain vehicle, and in which the riding vehicle 10 may be a motorcycle, such as a motorcycle, comprising: the riding vehicle comprises a frame 100, a power system 200, a steering system 300, a housing assembly 700, a walking system 800, and a load bearing system 900, the power system 200 including a power source 210 providing power, the power system 200 and the steering system 300 being supported by the frame 100, the steering system 300 being for controlling travel of the riding vehicle 10, the housing assembly 700 covering at least a portion of the frame 100, the load bearing system 900 including a seat cushion 910 for a user to ride on, the seat cushion 910 being disposed above the frame 100. Frame 100 supports power system 200, steering system 300, and load bearing system 900. The saddle-ride type vehicle further includes a propulsion system 800 and a drivetrain 830, the propulsion system 800 including wheels that can be driven by the powertrain 200, the wheels including front wheels 810 and rear wheels 820.

The first mounting member 21 and the second mounting member 22 are arranged in the front-rear direction, so that the vehicle frame 100 as a whole is more stable. The plate structure is relatively light compared to the tube structure, which can relatively reduce the weight of the vehicle frame 100. The thickness of the first mounting member 21 and the second mounting member 22 does not exceed 5mm, thereby ensuring the weight reduction of the vehicle frame 100 and ensuring the strength of the first mounting member 21 and the second mounting member 22. Optionally, the thickness of the first and second mounting

members

21, 22 does not exceed 3 mm.

The frame 100 can ensure the light weight of the frame and improve the strength of the frame at the same time by integrating the tube body, the non-tubular second frame member 20 and the third frame member 141, the third frame member 141 forms the first positioning portion 142 and the second positioning portion 143 connecting the main frame 110 and the third positioning portion 146 including at least two mounting power sources 210, the first positioning portion 142, the second positioning portion 143 and the third positioning portion 146 are distributed on the left and right sides, and the first positioning portion 142 and/or the second positioning portion 143 on the same side and the third positioning portion 146 on the same side are integrally formed. The subframe 120 is mounted and positioned by the subframe positioning portion 147 so that the center frame 140 connects the main frame 110 and the subframe 120 in the front-rear direction. The subframe positioning portions 147 are generated on the connecting members 144, so that the subframe positioning portions 147 are integrally molded with the first positioning portions 142, the second positioning portions 143, and the third positioning portions 146. The relative positions of the first pipe, the second pipe and the subframe 120 are more fixed.
