Rear Spring M2 Cyclone

【HYPERPRO 22091121 Rear Spring M2 Cyclone Suspension】
■Rear Spring
Suspension springs with a constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes in response to suspension movement.
It maintains a state that is neither too soft nor too hard, while also providing the strength to withstand 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. It absorbs fine bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike ordinary springs, there is no constant spring rate, so resonance does not occur.
●Springs are wound by computer-controlled machine tools, then shot-peened to remove microscopic surface scratches that could lead to performance degradation. Furthermore, each finished spring undergoes a performance inspection with a tester.
●In the Netherlands, Hyperpro's home country, all ambulance motorcycles are equipped with Hyperpro springs.
