Rear spring Softail FLSTC

【HYPERPRO Hyperpro 22092251 Rear Spring Softail FLSTC Suspension】
■Rear Spring
Suspension springs with a constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes to follow the movement of the suspension.
It maintains a state that is neither too soft nor too hard, and also has the ability to maintain stability during high-load cornering and sudden braking.
●Front springs come with the necessary amount of fork oil.
●Optimizes changes in caster during braking before a corner, making it easier to transition to the next action. Absorbs small bumps during cornering, eliminating 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 scratches on the surface that lead to performance deterioration. 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.
