When the motorcycle is going over bumps and slopes, it is particularly hard and bumpy. And when braking, the front of the vehicle noticeably sinks, it runs at high speed, veers during turns, and the handlebars shake. What do you think is the reason for this? Is it severe wear on the steering bearing? Or is there oil leakage in the shock absorber? The most obvious thing is to stop and take a look to see if there is any oil residue on the shock absorber rod, and whether it is wet. If there is oil stain or mud at the lower end of the shock absorber, it should be that the shock absorber is leaking oil.

   ~ How to solve it ~

1. Check and repair the piston rod 

Touch the piston rod with your hand. If you feel a slight roughness, it can be polished precisely to restore its smoothness and ensure the smoothness of the piston rod. If the surface is already very rough and deformed or bent, then the standard piston rod must be replaced. 2. Select high-quality and appropriately sized oil seals  When replacing the oil seal, do not choose those cheap and inferior oil seals. Select genuine motorcycle-specific oil seals with moderate hardness, standard structure, and appropriate elasticity;  At the same time, replace the spring ring when replacing the oil seal to ensure the appropriate lip pressure and reliable sealing.

3. Follow the standard assembly process  When assembling the oil seal, ensure cleanliness, dryness, precise alignment, adequate lubrication, and correct installation to avoid damage to the oil seal by human factors.  (The picture shows the assembly of the shock absorber)

4. Regular maintenance and correct usage  Of course, regular maintenance is also very important. Use high-quality and viscosity-appropriate shock absorber-specific oil; regularly clean the surface of the shock absorber of sand and mud to prevent impurities from entering the oil seal; avoid excessive impact, jumping, and heavy loads, and reduce the extreme load of the shock absorber. These are all good methods. 

In fact, the oil leakage mainly occurs in four aspects: the surface accuracy of the piston rod, the quality of the oil seal, the assembly process, and daily maintenance. As long as the cause is identified, the right parts are used, proper maintenance is carried out, and scientific upkeep is implemented, the lifespan of the shock absorber can be significantly extended, making the riding more stable, more comfortable, and safer.
