Front Spring Sportster XL1200 XL883

【HYPERPRO Hyperpro 22092760 Front Spring Sportster XL1200 XL883 Suspension Fork Spring】
■Front Spring
A 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 the change in caster during braking before a corner, facilitating the next action. Absorbs small gaps during cornering, eliminating vibrations that disturb the rider.
●Unlike ordinary springs, there is no constant spring rate, so resonance does not occur.
●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 Hyperpro's home country of the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.
