Some knowledge about motorcycle shock absorber

Shock absorber is a important part of motorcycle structure. It not only supports bodywork but also absorber the momentum.
So that it can enhance driving comfort and stability. Finally, it extend motorcycle's using age.
Due to many kinds of models, there are various structure of shock absorber. But the keystone is the same that it absorbs
The momentum kinetic energy into heat energy using spring, hydraulic pressure oil and air. The aims is to absorb the momentum.
Shock absorber includes front absorber and back absorber. Back absorber is simple and made up of absorb spring and damper.
It has good bounce and it's always unable to take-down. Some of the back absorber has the adjust items which can adjust spring's flexibility.
Front absorber is a bit complicated and take great influence on motorcycle.Front absorber not only absorb front wheel's shock but also pass the running power.
So it demands a good flexibility. Moreover two absorber's flexibility should be the same in order to keep the motorcycle driving straight.
Front absorber librates 80 times/min, it requires good toughness spring and front fork core. It also requires high produce precision and toughness. Concretely front fork core should never been damaged or distorted, otherwise it affects absorber's effect, increase abrasion. Front fork's belt limit is 0.1mm to 0.2mm, it will be changed over 0.2mm.
Moreover, oil seal is also very important because it's hard to seal reciprocate than whirligig. Oil seal's material have to be good rubber and be spring.
Shock absorber should be removed by expert in order not to do harm to shock absorber.Front fork and oil seal take a great influence on motorcycle driving. Drivers should use original fittings for Front fork and oil seal.
