Front Fork Springs for Sportster XL883N XL1200NS

[HYPERPRO 22093540 Front Spring Sportster XL883N XL1200NS Suspension Fork Spring]
■Front Spring
Suspension spring 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 provides the strength to endure high-load cornering and sudden braking.
●Optimizes the change in caster during braking before a corner, making it easier to transition to the next action. It absorbs small bumps during cornering and eliminates vibrations that interfere with 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 a performance inspection using a tester.
●In the Netherlands, Hyperpro's home base, all emergency motorcycles are equipped with Hyperpro springs.
