Front Spring Touring FLH

[HYPERPRO 22093330 Front Spring Touring FLH Suspension Fork Spring] ■Front Spring Suspension springs with a constant rising rate, uniquely designed by Hyperpro. The spring rate constantly changes in response to suspension movement. Maintaining a state that is neither too soft nor too hard, it also possesses the power to withstand 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 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 inspection by a tester. ●In Hyperpro's home country, the Netherlands, all emergency motorcycles are equipped with Hyperpro springs.
