Front spring TDM850

【HYPERPRO 22031180 Front Spring TDM850 Suspension Fork Spring】
■Front Spring
A suspension spring 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.
●Optimizes changes in caster during braking before a corner, facilitating the transition to the next action. It absorbs minor bumps during cornering, eliminating vibrations that would hinder the rider.
●Unlike conventional 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 a performance inspection by a tester.
●In the Netherlands, where Hyperpro is based, all emergency motorcycles are equipped with Hyperpro springs.
