A motorcycle rear shock absorber is a device that absorbs vibration and shock caused by road irregularities when riding a motorcycle.
It is usually located at the rear of the motorcycle, attached to the swingarm, between the frame and the rear wheel, and works by compressing and decompressing a fluid, such as oil or air, to absorb the movements of the wheel.
High quality rear shock absorbers can significantly improve a motorcycle's stability and ride comfort .
Why change your motorcycle rear shock absorbers?
There are several reasons why you might want to change your motorcycle's rear shock absorbers:
Wear : Shock absorbers can wear out over time, which can lead to loss of performance and safety. If you notice your bike pitching or the rear wheel bouncing excessively, it may be time to change your shocks.

It is important to note that it is always best to consult a professional mechanic to check the condition of your shock absorbers and advise you on the best option on motorcycle models. There are also reconditioning solutions, mainly on the most high-end models.
What types of motorcycle shock absorbers are there?
There are mainly two types of motorcycle shock absorbers: spring shock absorbers and gas shock absorbers.
Spring shock absorbers : Spring shock absorbers are the most common and the oldest. They use a metal spring to absorb road vibrations and shocks. Spring shocks can be tuned to suit different types of riding and loads.
Gas shock absorbers : Gas shock absorbers use a fluid, usually oil or compressed air, to absorb road vibrations and shocks. Gas shocks tend to be lighter and more durable than spring shocks. They can also be tuned to accommodate different types of riding and loads.
There are also semi-active and active dampers, which use sensors and algorithms to automatically adjust based on driving conditions. These shock absorbers are generally used on high-end and sports motorcycles.
What are the risks of riding with hs shock absorbers?
Driving with shock absorbers in poor condition can cause many safety and performance issues:
Stability : Shock absorbers in poor condition can cause a lack of stability when riding, which can lead to sudden and unexpected movements of the motorcycle. This can increase the risk of a fall or collision.
Driving comfort : Shock absorbers in poor condition can cause unpleasant vibrations and jolts when riding, which can make driving less comfortable and tiring.
Premature Wear : Shock absorbers in poor condition can lead to premature wear of tires, bearings and other motorcycle components.
Performance : Shock absorbers in poor condition can lead to a loss of motorcycle performance, especially with regard to handling, handling and grip.
Safety : Shock absorbers in poor condition can increase the risk of accidents, especially when riding on rough roads or in difficult conditions.
It is important to have your motorcycle's shock absorbers serviced regularly to ensure that they are working properly. Replace damaged or worn shock absorbers to ensure the safety and performance of your motorcycle. If your shock absorber is too crushed then do not use a motorcycle shock absorber raiser to make up for this failure.
How do I know if my shock absorbers need to be replaced?
There are several signs that may indicate that your motorcycle shock absorbers need to be replaced:
Excessive bouncing : If your motorcycle's rear wheel is bouncing excessively when riding on rough or uneven roads, it could be a sign that your shock absorbers are no longer working effectively.
