Front Spring YZF-R1

[HYPERPRO 22031380 Front Spring YZF-R1 Suspension Fork Spring]
■Front Spring
Suspension springs 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 withstand high-load cornering and sudden braking.
●Optimizes the caster change during braking before a corner, making it easier to transition to the next action. It absorbs small bumps during cornering, eliminating vibrations that disturb the rider.
●Unlike regular 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 surface scratches that can lead to performance degradation. Furthermore, after completion, each spring undergoes performance inspection by a tester.
●In the Netherlands, Hyperpro's home base, all ambulance motorcycles are equipped with Hyperpro springs.
