(1) What problems will occur if shock absorbers are not maintained?

Shock absorbers are not disposable items. They are composed of shock-absorbing oil, nitrogen, seals, pistons and springs inside. After long-term use, they will gradually age or wear out. Common problems include:

1. The shock-absorbing oil has deteriorated or leaked

The oil inside the shock absorber is the core for maintaining its damping effect. If it is not replaced for a long time or the sealing parts age and leak, the damping capacity will significantly decrease, manifested as a distinct "spring-like" feeling, and the rebound is either too fast or too slow.

2. The sealing ring has aged

Once the sealing ring ages, it will cause oil leakage, dust intrusion, internal structure wear and even rust.

3. Piston wear or jamming

After long-term use, the piston rod may show scratches and jamming, and the shock absorption action will not be smooth, especially in high-frequency vibrations, the impact is particularly significant.

4. Air mixed into the oil

It causes a "hole" effect, resulting in unstable damping force and affecting handling and comfort.

So, how often should shock absorbers be maintained to be reasonable?

It depends on your usage intensity, vehicle model and the structure of the shock absorber.

But general advice:

Usage environment

_

Suggested maintenance cycle

Daily urban cycling

_

Check every 8,000 to 12,000 kilometers

Long-distance crossing/motorcycle travel

_

Check before and after each motorcycle trip

Off-road/competitive use

_

Maintenance is required at 3,000 to 5,000 kilometers or after each race

Modified shock absorbers (such as Andreani

_

According to the professional calibration cycle, maintenance should be carried out once a year

Special note: Even if the mileage is less than one year, it is recommended to have a comprehensive inspection after using it for more than one year, because aging and wear are not entirely dependent on "running out".

(2) What exactly should be done for shock absorption maintenance?

Professional shock absorption maintenance is not as simple as "cleaning + oiling". It usually includes the following steps:

Disassemble the shock absorber assembly

2. Thoroughly clean all components and internal channels

3. Inspect/replace the sealing ring, oil dust seal and guide wear-resistant ring

4. Replace the shock-absorbing oil and remove air bubbles

5. Refill with nitrogen

Reassemble and test the damping performance
