Front springs: Zephyr 400/X

【HYPERPRO Hyperpro 22073010 Front Spring Zephyr 400/X Suspension Fork Spring】
■Front Spring
Suspension springs with a constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes in response to the movement of the suspension.
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. It absorbs small bumps during cornering, eliminating vibrations that hinder the rider.
●Unlike ordinary springs, there is no constant spring rate, so there is no resonance.
●Springs wound by computer-controlled machine tools are shot-peened to remove minute surface scratches that can lead to performance degradation. Furthermore, after completion, each spring undergoes performance inspection by a tester.
●In the Netherlands, Hyperpro's home country, all emergency motorcycles are equipped with Hyperpro springs.
