Front Springs Softail FLSTC FLSTF FLSTN

【HYPERPRO 22092880 Front Spring for Softail FLSTC FLSTF FLSTN 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.
It maintains a state that is neither too soft nor too hard, while also providing the strength to withstand 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 minor bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike conventional 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 could lead to performance degradation. Furthermore, after completion, each spring undergoes performance testing by a tester.
●In the Netherlands, Hyperpro's home country, all emergency motorcycles are equipped with Hyperpro springs.
