The main function of the motorcycle shock absorber is to slow down, absorb the shock and vibration transmitted to the wheel due to uneven road surface, and transmit force and torque; it also plays an important role in the smoothness and safety of motorcycle driving. The following should be noted:

1. Keep the shock absorber clean.

2. Regularly check whether the shock absorber spring is deformed and whether the shock absorber is loose.

3. For hydraulic shock absorbers, you should also check whether there is oil leakage, check whether the shock absorber oil is sufficient, and replace the shock absorber oil regularly. Usually, the shock absorber oil should be replaced once a year. When replacing, first unscrew the oil drain plug. , Drain the old oil into the basin. In order to drain the old oil in the shock absorber, you should hold the brake handle tightly and press the direction handle down repeatedly. After the old oil is drained, line up the other side to reduce Remove the shock absorbing oil of the shock absorber, then unscrew the compression nut on the top of the inner tube. Add kerosene or gasoline from the filling hole to clean it, and finally add the shock absorbing oil of the specified grade and capacity according to the requirements of the vehicle manual.

At present, many people have a misunderstanding in motorcycle maintenance, which is passive repair after the shock absorber has a problem, and they do not pay attention to the timely replacement of shock absorber oil during maintenance.

As we all know, oil plays an important role in the engine. Without oil lubrication, the normal operation of the engine will not be possible. The role of shock absorber oil in shock absorbers is often ignored by some motorcycle maintenance personnel. In fact, the shock absorber oil is the "blood" in the shock absorber. It not only has the functions of lubrication and rust prevention, but also maintains the damping characteristics of the shock absorber. Therefore, if the shock absorber oil is not replaced according to the regulations, the shock absorber oil will deteriorate. The deteriorated shock absorber oil will not only lose the above functions, but also aggravate the wear of the shock absorber components, resulting in oil leakage. The elasticity of the shock absorber after oil leakage decreases, and the axis of the plunger rod is inclined, which causes abnormal wear of the plunger, and forms scratches and grooves. The shock absorber after oil leakage will make its elasticity uneven, resulting in the offset of the motorcycle's center of gravity and destroying the balance performance of the vehicle. When riding, there will be medium and high-speed wheel swings, which will bury hidden dangers for driving safety.

It can be seen from the above analysis that timely replacement of shock absorber oil is an important part of motorcycle maintenance. No matter how good the shock absorber components are, if the shock absorber oil is not replaced in time, it will seriously affect the technical performance and safety performance of the motorcycle. Likewise, not using a good quality shock oil can have bad consequences. Therefore, for the safety of users and the reputation of maintenance personnel, during maintenance, it is necessary to replace the motorcycle shock absorber oil in time and use high-quality shock absorber oil!
