Rear spring FZR1000

【HYPERPRO Hyperpro 22031191 Rear Spring FZR1000 Suspension】
■Rear Spring
Suspension spring with constant rising rate uniquely designed by Hyperpro.
The spring rate constantly changes in accordance with the suspension's movement.
It maintains a state that is neither too soft nor too hard, and also has the ability to maintain stability during high-load cornering and sudden braking.
●Front springs come with the necessary amount of fork oil.
●Optimizes caster changes during braking before corners, making it easier to transition to the next action. Absorbs small gaps during cornering and eliminates vibrations that interfere with the rider.
●Unlike conventional 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 with a tester.
●In the Netherlands, where Hyperpro is based, all emergency motorcycles are equipped with Hyperpro springs.
