Rear Spring FZR400RR

【HYPERPRO 22033031 Rear Spring for FZR400RR 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, and also provides the resilience needed during high-load cornering and sudden braking.
●Front springs come with the necessary amount of fork oil.
●Optimizes changes in castor during braking before corners, facilitating the next maneuver. Absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike ordinary springs, there is no constant spring rate, so resonance does not occur.
●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 testing by a tester.
●In the Netherlands, Hyperpro's home base, all emergency motorcycles are equipped with Hyperpro springs.
