The shock absorber is an important device of the motorcycle. The function of the motorcycle shock absorber is to alleviate and attenuate the impact and vibration of the motorcycle during driving, and ensure the smoothness and comfort of the driving, which is beneficial to improve the service life of the motorcycle. And the stability of manipulation. The following article analyzes the classification and selection of motorcycle shock absorbers for your reference .

Classification of shock absorbers

According to different characteristics and directions, shock absorbers can be divided into the following categories:

(1) Attenuation force direction: one-way action damper / two-way action damper.

(2) Load adjustment type: spring initial pressure adjustment type / gas spring type / installation angle adjustment type.

(3) Structural form: telescopic tube type front hydraulic shock absorber / rocker type shock absorber / rocker lever vertical center shock absorber / rocker lever tilt type center shock absorber.

(4) Cylinder position: inverted shock absorber / upright shock absorber.

(5) According to the working medium: spring type shock absorber / force damping type shock absorber / oil - gas combined front  shock absorber / nitrogen filled hydraulic shock absorber.



Hydraulic damping rear shock absorber principle

(1) Hydraulic shock absorber is the most common shock absorber used in motorcycles. The structure of hydraulic shock absorber is basically similar to that of suction pump. The difference is that the upper end of the steel body of the hydraulic shock absorber is closed. There are small holes in the valve.

(2) When the rear wheel encounters a bumpy road surface, the cylinder moves upward and the piston moves relatively downward in the inner cylinder. At this time, the piston valve is flushed upward, and the oil on the lower side of the piston in the inner cylinder chamber flows to the upper side of the piston without any resistance.


(3) At the same time, this part of the oil also flows into the oil chamber between the inner and outer cylinders through small holes in the bottom valve.

(4) This effectively attenuates the impact load of the bumpy road surface on the vehicle.

(5) When the wheel falls over the raised ground, the cylinder will also move downward, and the piston will move upward relative to the cylinder.

(6) When the piston moves upward, the oil flushing the bottom valve flows to the inner cylinder, while the oil on the upper side of the inner cylinder piston flows downward through the small hole in the piston valve.

(7) At this time, when the oil flows through the small hole, it will be subjected to a large resistance, which produces a good damping effect and serves the purpose of damping.


The shock absorption technology of motorcycles is constantly developing. The popularity of these new technologies can quickly attenuate the impact and vibration caused by changes in vehicle speed, load and various road conditions, and automatically adjust to the best technical state, which greatly improves the shock absorption performance and improves the adaptability, comfort, stability and safety of the motorcycle ride.
