Why is necessary to use spring shockers in motorcycles?
Answers
COMPRESSION DAMPING
Rear suspension can be split into two: Low speed and High speed damping.
What this refers to is how fast the shaft of the shock is moving, too little and the suspension is uncontrolled and too much the bike can feel harsh. If you are riding a bumpy trail for example and the wheel is forced upwards, the compression circuit controls the speed at which the suspension squeezes. The damping helps the spring from using too much travel. It’s important to balance the compression damping and spring for good handling and also combat bottoming out, while having enough movement to get over bumps nicely.
If you’d like to adjust your damping check out how best to do this on your bike in your manual, but it usually involves turning the adjuster at the top of the absorber reservoir.
Too much damping can result in excessive resistance to the movements and therefore you cannot use the full suspension travel. Too little the bike can feel unstable as its travelling through the full stoke.
