What is the rear shock spring on a motorcycle?

The rear shock spring is the basic part of the motorcycle and plays two primary roles: Sustaining the load of the rear of the bike with a bump softening effect, and preventing any up and down shakes of the suspension by supplying the balance. The rear shock spring absorbs the unwanted shock or vibrations of the back side of the motorcycle.
The front shock spring is circular steel wires pressed into the fork lines or covered around shock parts. Front shock springs keep up the bike and balance both the fixed burden of the bike and the rider, but are also attached to adjust expected shock to the front of the motorcycle.

Working of the shock springs

The rear shock spring is connected to the motorcycle´s rear swingarm and the shock absorber, which is responsible for controlling the rate at which the spring compresses and rebounds. When a rider encounters a bump or uneven surface, the rear shock spring compresses, absorbing the impact and helping to keep the motorcycle stable and in control. When the rider exits the bump, the spring rebounds and returns to its normal position, ready to absorb the next impact.
If your spring’s pace is 1 kg/mm, when you squeeze the spring by 1mm, it will put a strength of 1kg back. When you spin the preload regulator and count 6mm of automated contraction, the spring would apply 5kg back. To squeeze it further, you’d require more than 5 kg of pressure.
The spring rate stays exact, but you adjust how the spring responds to its weight when revving, taking turns, and braking.
Strong braking and acceleration apply more pressure and the spring absorbs the shock or jerk with the same intensity.
The brands that offer front and rear shock springs are Rtech, Öhlins, Athena, Kuryakyn, and Hyperpro.
