Front Spring CBR900RR

【HYPERPRO Hyperpro 22011020 Front Spring CBR900RR Suspension Fork Spring】
■Front Spring
Suspension spring 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, and also provides the resilience needed during high-load cornering and sudden braking.
●Optimizes changes in caster during braking before corners, making it easier to transition to the next action. It absorbs small bumps during cornering, eliminating vibrations that would interfere with the rider.
●Unlike regular 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 can lead to performance degradation. Furthermore, after completion, each spring undergoes performance inspection by a tester.
●In the Netherlands, Hyperpro's home base, all emergency motorcycles are equipped with Hyperpro springs.
