Front Spring Ducati ST4

【HYPERPRO Hyperpro 22093320 Front Spring Ducati ST4 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 suspension's movement.
It maintains a state that is neither too soft nor too hard, and also provides the resilience needed 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 hinder the rider.
●Unlike conventional 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 scratches on the surface that can lead to performance degradation. Furthermore, each spring undergoes a performance inspection by a tester after completion.
●In the Netherlands, Hyperpro's home country, all emergency motorcycles are equipped with Hyperpro springs.
