Front springs GPZ900R

【HYPERPRO 22071220 Front Spring for GPZ900R - Suspension Fork Spring】
■Front Spring
Suspension springs 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.
●Optimizes caster changes during braking before a corner, making it easier to transition to the next action. Absorbs small bumps during cornering, eliminating vibrations that disturb the rider.
●Unlike conventional springs, there is no constant spring rate, so resonance does not occur.
●Springs wound by computer-controlled machine tools are shot-peened to remove minute surface scratches that lead to performance degradation. Furthermore, after completion, each spring undergoes performance testing by a tester.
●In the Netherlands, HYPERPRO's home country, all ambulance motorcycles are equipped with HYPERPRO springs.
