Rear Spring Dyna FXDB

【HYPERPRO Hyperpro 22091681 Rear Spring Dyna FXDB 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 maintain stability during high-load cornering and sudden braking.
●Front springs come with the necessary amount of fork oil.
●Optimizes caster changes during braking before a corner, making it easier to transition to the next action. Absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike conventional 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 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.
