Front spring Softail FLSTF

【HYPERPRO 22091060 Front Spring Softail FLSTF Suspension Fork Spring】
■Front Spring
Suspension springs with a constant rising rate, uniquely designed by HYPERPRO.
The spring rate constantly changes in accordance with the suspension's movement.
It maintains a state that is neither too soft nor too hard, and also provides the necessary force during high-load cornering and sudden braking.
●Optimizes caster changes during braking before a corner, making it easier to transition to the next action. It absorbs small bumps during cornering, eliminating vibrations that disturb the rider.
●Unlike conventional springs, there is no fixed spring rate, so resonance does not occur.
●Springs wound by computer-controlled machine tools are shot-peened to remove minute surface scratches that lead to performance degradation. Furthermore, after completion, each spring undergoes a performance test by a tester.
●In the Netherlands, where HYPERPRO is based, all emergency motorcycles are equipped with HYPERPRO springs.
