Rear Spring YZF-R1

【HYPERPRO Hyperpro 22031991 Rear Spring YZF-R1 Suspension】
■Rear Spring
Suspension spring 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.
●Front springs come with the necessary amount of fork oil.
●It optimizes the change in caster during braking before a corner, making it easier to transition to the next action. It absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike conventional 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 scratches on the surface that lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection using a tester.
●In the Netherlands, Hyperpro's home base, all emergency motorcycles are equipped with Hyperpro springs.
