Problems solved by technology

[0002] At present, two front shock absorbers are respectively arranged on the left and right sides of the motorcycle, and the structures of the two front shock absorbers are all the same. Shock absorbing springs and damping valve trains are all housed in the two shock absorbers, but their functions It is the same. This structure not only increases the weight of the shock absorber, but also the production cost is relatively high. In addition, the length of the shock absorber spring of the front shock absorber of the motorcycle is longer, and the outer diameter of the spring has a gap with the inner diameter of the front fork tube. Relatively small, when reciprocating, due to the relatively large diameter of the shock-absorbing spring being compressed and bent, the shock-absorbing spring shakes in the front fork tube and the bottom, and then hits the inner wall of the front fork tube port to cause friction, produce abnormal noise, and affect The comfort of motorcycle riding
