Front Spring ZXR750

[HYPERPRO 22071110 Front Spring ZXR750 Suspension Fork Spring]
■Front Spring
Suspension springs with a constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes in response to suspension movement.
It maintains a state that is neither too soft nor too hard, and also has the ability to maintain stability during high-load cornering and sudden braking.
●Optimizes changes in caster during braking before a corner, making it easier to transition to the next action. Absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike conventional springs, there is no constant spring rate, so resonance does not occur.
●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic surface scratches that lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection by a tester.
●In Hyperpro's home country of the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.
