Rear Spring YZF-R1

【HYPERPRO Hyperpro 22031611 Rear Spring YZF-R1 Suspension】
■Rear Spring
A suspension spring with a constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes in response to the suspension's movement.
It maintains a state that is neither too soft nor too hard, and also has the ability to resist high-load cornering and sudden braking.
●Front springs come with the necessary amount of fork oil.
●Optimizes changes in caster during braking before a corner, making it easier to transition to the next action. Absorbs fine bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike regular springs, there is no constant spring rate, so resonance does not occur.
●Springs wound on computer-controlled machine tools are shot-peened to remove microscopic surface scratches that can lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection by a tester.
●In Hyperpro's home country of the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.
