Professionally analyze motorcycle faults and accurately recommend the required models.

If there is a left and right swing on the way of the motorcycle, in addition to the speed of the car is too fast, it is also inseparable from the design of the vehicle itself, and the exclusion of these two factors is related to the following reasons.

1. The deformation of the rim, if the rim of the motorcycle is out of round, it will cause the motorcycle to sway left and right, especially the front ring, and this phenomenon occurs mostly on the rim of the structure of the car.

2. The clearance is too large, here specifically refers to the rear fork of the motorcycle, because the connection part of the rear fork and the frame has a buffer sleeve. If the buffer sleeve is excessively worn, the gap between the frame and the fork will be too large. Once the gap is too large, it will cause the motorcycle to swing during driving.

3. Bearing damage, whether it is a pressure bearing or front and rear wheel bearings, once damaged or excessive clearance, it will cause the motorcycle to swing during driving.

4. Shock absorbers, if the left and right shock absorbers are different in hardness and hardness, the vehicle will also swing from side to side during the driving process, but its performance will not be obvious and will only appear under certain circumstances, such as In case of cornering or weight bearing.

In addition to the above four reasons, the frame deformation, tire installation is not in place, the slack of the car, excessive pressure and other details, it will also cause the motorcycle to shake during driving.

Through the above introduction, we can see that if there is a left and right swing during the running of the motorcycle, it still has a certain relationship with the shock absorber, especially under the premise of oil leakage of the shock absorber, so the shock absorber is also a rule to eliminate this fault. Parts that need attention.
