Front Spring TDM900

【HYPERPRO Hyperpro 22031460 Front Spring TDM900 Suspension Fork Spring】
■Front 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, while also providing the strength to withstand high-load cornering and sudden braking.
●Optimizes the caster change during braking before a corner, making it easier to transition to the next action. It absorbs small bumps during cornering, eliminating vibrations that would hinder the rider.
●Unlike ordinary 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 could lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection by a tester.
●In Hyperpro's home country of the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.
