Rear spring Ducati ST4S

【HYPERPRO Hyperpro 22092901 Rear Spring Ducati ST4S 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 provides the resilience needed during 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, making it easier to transition to the next action. It 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 are wound by computer-controlled machine tools and then shot-peened to remove microscopic surface scratches that could lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection using a tester.
●In the Netherlands, Hyperpro's home base, Hyperpro springs are installed on all emergency motorcycles.
