Front Spring Dyna FXDF

[HYPERPRO 22093620 Front Spring Dyna FXDF 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 has the ability to maintain stability 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. It absorbs small gaps during cornering and eliminates vibrations that interfere with the rider. ●Unlike ordinary 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 lead to performance degradation. Furthermore, after completion, each spring undergoes performance inspection by a tester. ●In the Netherlands, Hyperpro's home base, all emergency motorcycles are equipped with Hyperpro springs.
