Rear Spring Ninja 650 Ninja 400/R

【HYPERPRO 22071801 Rear Spring Ninja 650 Ninja 400/R Suspension】
■Rear 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.
●Front springs come with the necessary amount of fork oil.
●Optimizes changes in caster during braking before a corner, facilitating the transition to the next action. Absorbs small bumps during cornering, eliminating vibrations that bother 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, after completion, each spring undergoes performance testing by a tester.
●In the Netherlands, Hyperpro's home country, Hyperpro springs are installed on all emergency motorcycles.
