Front Spring Ninja 400/R Ninja 650

【HYPERPRO 22071800 Front Spring Ninja 400/R Ninja 650 Suspension Fork Spring】
■Front Spring
A suspension spring 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 has the ability 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. 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 surface scratches 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.
