Front Springs Sportster XL1200X

【HYPERPRO 22093280 Front Spring Sportster XL1200X Suspension Fork Spring】
■Front Spring
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, and also provides the necessary resilience during high-load cornering and sudden braking.
●Optimizes caster changes during braking before corners, facilitating the transition to the next action. It absorbs small bumps during cornering, eliminating vibrations that could disturb 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 minute surface scratches that could lead to performance degradation. 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.
