Front Spring 690 SMC

【HYPERPRO Hyperpro 22091840 Front Spring 690 SMC 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, while also having the strength to withstand high-load cornering and sudden braking.
●Optimizes the change in caster during braking before a corner, facilitating the transition to the next action. It absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike regular springs, there is no constant spring rate, so resonance does not occur.
●Springs wound by computer-controlled machines are shot-peened to remove microscopic surface scratches that could lead to performance degradation. Furthermore, each spring undergoes performance inspection by a tester after completion.
●In the Netherlands, Hyperpro's home country, all emergency motorcycles are equipped with Hyperpro springs.
