Front Springs 990 Super Duke

[HYPERPRO Hyperpro 22091850 Front Spring 990 Super 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, and also has the strength to withstand high-load cornering and sudden braking.
●Optimizes changes in caster during braking before a corner, facilitating the transition to the next action. Absorbs small bumps during cornering, eliminating vibrations that hinder the rider.
●Unlike regular springs, there is no constant spring rate, so there is no resonance.
●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.
