Front Spring FZ400

【HYPERPRO 22033060 Front Spring FZ400 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. It absorbs minor gaps during cornering, eliminating vibrations that interfere with the rider.
●Unlike ordinary springs, there is no constant spring rate, so resonance does not occur.
●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic surface scratches that 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.
