Front Spring CBR900RR

【HYPERPRO 22011070 Front Spring CBR900RR 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 change 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, 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 inspection by a tester.
●In the Netherlands, Hyperpro's home country, Hyperpro springs are installed on all ambulance motorcycles.
