Front Spring DR-Z400S

【HYPERPRO Hyperpro 22053040 Front Spring DR-Z400S 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 movement of the suspension.
It maintains a state that is neither too soft nor too hard, and also provides the strength to hold up during 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 gaps during cornering and eliminates vibrations that interfere with the rider.
●Unlike ordinary 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 scratches on the surface that can lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection by a tester.
●In the Netherlands, where Hyperpro is headquartered, all emergency motorcycles are equipped with Hyperpro springs.
