At this time, the rear wheel 121 of the motorcycle 100 moves to the highest position, and the mounting bracket 124 and the power assembly 13 are lifted to the highest position, at which time the position of the connecting point between the mounting bracket 124 and the shock absorber 123 is defined as the first rear limit position P11. The rear cross pipe 1512 is rotatably connected to the power assembly 13, and the position of the connecting point between the rear cross pipe 1512 and the power assembly 13 is defined as the first front limit position P21.

The included angle between the first straight line L1 and the second straight line L2 is θ, which is greater than or equal to 4° and less than or equal to 6°.

[0052] In some embodiments, the included angle θ between the first straight line L1 and the second straight line L2 is equal to 5.3°.

[0053] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the length of the limiting plate 157 is S1, the distance between the center axis of the front cross pipe 1511 and the center axis of the rear cross pipe 1512 is S2, and the ratio of S1 to S2 is greater than or equal to 0.5 and less than or equal to 0.7.

[0054] In some embodiments, the ratio of S1 to S2 is equal to 0.6.

[0055] According to the lever principle, since the ratio of S1 to S2 is equal to 0.6, the vibration and amplitude transmitted to the frame 11 by the rear wheel 121 can be reduced by about 60%. At the same time, the left and right buffer sleeves 155 and 156 installed in the front cross pipe 1511 can absorb the width direction vibration, effectively reduce the vibration of the frame 11, relieve the vibration and discomfort of the motorcycle 100 caused by the large up-down amplitude of the rear wheel 121 when passing through a bumpy road section, and alleviate the uncomfortable vibration, impact and noise caused by uneven road surface, thereby improving the driving smoothness, stability and riding comfort.
