Front Spring TRX850

[HYPERPRO 22031070 Front Spring TRX850 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 changes in caster during braking before a corner, making it easier to transition to the next action. Absorbs small bumps during cornering, eliminating vibrations that disturb 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 a performance inspection by a tester. ●In Hyperpro's home country of the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.
