Rear spring ZZR1100C ZZR1100D

[HYPERPRO 22071021 Rear Spring ZZR1100C ZZR1100D Suspension]
■Rear Spring
A suspension spring with a constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes in response to the suspension's movement.
It maintains a state that is neither too soft nor too hard, while also providing the strength to withstand high-load cornering and sudden braking.
●Front springs come with the necessary amount of fork oil.
●Optimizes changes in caster during braking before a corner, making it easier to transition to the next action. Absorbs small bumps during cornering and eliminates vibrations that interfere with the rider.
●Unlike ordinary springs, it does not have a constant spring rate, so it does not resonate.
●Springs wound on computer-controlled machine tools are shot-peened to remove microscopic surface scratches that can lead to performance degradation. Furthermore, after completion, each spring undergoes performance testing by a tester.
●In the Netherlands, Hyperpro's home base, all emergency motorcycles are equipped with Hyperpro springs.
