1. Principle: When the wheel falls over the raised ground, the cylinder will also move downward, and the piston will move upward relative to the cylinder. When the piston moves upward, the oil rushes through the valve at the bottom and flows to the inner cylinder. At the same time, the oil on the upper side of the piston of the inner cylinder flows to the lower side through the small hole on the piston valve. At this time, when the oil flows through the small hole, it will receive a lot of resistance, which produces a better damping effect and plays the purpose of damping.

2. There are two suspension components on the motorcycle: one is located at the front wheel, usually called the front fork; the other is located at the rear wheel, usually called the rear shock absorber.

3. The main function of the suspension of motorcycles is the same as that of cars: absorbing the vibration of the body caused by uneven ground, making the whole riding more comfortable; at the same time, keeping the tires in contact with the ground to ensure the power output of the tires to the ground.

4. Unlike a car, the suspension setting of a motorcycle will greatly affect the handling and cornering stability of the motorcycle. Of course, the car suspension settings will also have an impact on the handling, but we generally do not require too much on the performance of the family car, as long as it is comfortable enough.

5. Suspension is generally composed of two parts: spring and damper.

6. The spring is the main body of the suspension. This kind of spring is very similar to the spring in the ball pen we usually use, but it is much stronger. The spring absorbs the impact of the ground through tension and at the same time ensures the contact between the tire and the ground; the damper is a device used to control the tension and rebound force of the spring.

7. The damper is like a pump filled with oil. The speed at which the air pump moves up and down depends on the size of the oil supply hole and the viscosity of the oil. All cars have springs and dampers. On the front fork, the spring is hidden inside; while on the rear shock absorber, the spring is exposed to the outside. The suspension on the front and rear wheels works separately, and can respond separately according to the road surface and riding style.
