Rear spring ZXR400

【HYPERPRO Hyperpro 22073051 Rear Spring ZXR400 Suspension】
■Rear 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, and also has the ability to withstand high-load cornering and sudden braking.
●Front springs come with the necessary amount of fork oil.
●It optimizes caster changes during braking before corners, making it easier to transition to the next action. It absorbs minor bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike ordinary springs, there is no constant spring rate, so there is no resonance.
●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 inspection by a tester.
●In Hyperpro's home country of the Netherlands, all emergency motorcycles are equipped with Hyperpro springs.
