Front Spring SRX400 SRX600

【HYPERPRO 22033020 Front Spring for SRX400 SRX600 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, while also providing the strength 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. Absorbs small bumps during cornering, eliminating vibrations that would interfere with 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, each spring undergoes a performance test with a tester after completion.
●In Hyperpro's home country, the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.
