Front spring 620-E Duke

【HYPERPRO 22091650 Front Spring 620-E Duke Suspension Fork Spring】
■Front Spring
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 handle high-load cornering and sudden braking.
●Optimizes caster changes during braking before corners, making it easier to transition to the next action. Absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike ordinary springs, it does not have a constant 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 a performance test by a tester.
●In the Netherlands, Hyperpro's home country, all emergency motorcycles are equipped with Hyperpro springs.
