Rear Spring YZF-R1

[HYPERPRO 22032241 Rear Spring YZF-R1 Suspension]
■Rear Spring
Suspension springs with a constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes in response to the suspension's movement.
This maintains a state that is neither too soft nor too hard, while also providing the strength to withstand 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. Absorbs small gaps during cornering, eliminating vibrations that bother the rider.
●Unlike ordinary springs, there is no fixed spring rate, so there is no resonance.
●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic scratches on the surface that can lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection with a tester.
●In the Netherlands, Hyperpro's home country, all ambulance motorcycles are equipped with Hyperpro springs.
