Rear Spring CBR900RR

[HYPERPRO 22011021 Rear Spring CBR900RR Suspension]
■Rear 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 resilience needed during high-load cornering and sudden braking.
●Front springs come with the necessary amount of fork oil.
●Optimizes caster changes during braking before a corner, making it easier to transition to the next action. It absorbs small bumps during cornering, eliminating vibrations that disturb 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 imperfections that can lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection by a tester.
●In Hyperpro's home country, the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.
