Combi Kit Front & Rear Springs Softail FLST

【HYPERPRO HyperPro 22091062 Combi Kit Front & Rear Spring Softail FLST Suspension】
■ Combi Kit
Suspension springs 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, while also providing the strength to withstand high-load cornering and sudden braking.
● The front spring comes with the necessary amount of fork oil.
● It 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, it does not have a constant spring rate, so it does not resonate.
● 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 testing by a tester.
● In Hyperpro's home country of the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.
