Front Spring ZZR400 ZZR600

【HYPERPRO Hyperpro 22073040 Front Spring ZZR400 ZZR600 Suspension Fork Spring】
■Front 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 having the strength to withstand high-load cornering and sudden braking.
●Optimizes caster changes during braking before corners, making it easier to transition to the next action. It absorbs small gaps during cornering, eliminating vibrations that interfere with the rider.
●Unlike regular springs, there is no fixed spring rate, so it does not resonate.
●Springs wound by 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 inspection by a tester.
●In the Netherlands, Hyperpro's home country, all emergency motorcycles are equipped with Hyperpro springs.
