Front Spring XJ900S

【HYPERPRO Hyperpro 22031930 Front Spring XJ900S Suspension Fork Spring】
■Front Spring
Suspension springs with a constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes in accordance with the suspension's movement.
This maintains a state that is neither too soft nor too hard, and also provides the necessary resilience during high-load cornering and sudden braking.
●Optimizes the change in caster during braking before a corner, making it easier to transition to the next action. Absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike conventional springs, there is no constant spring rate, so there is no resonance.
●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic surface scratches that could lead to performance degradation. Furthermore, each finished spring undergoes a performance inspection by a tester.
●In the Netherlands, Hyperpro's home base, all emergency motorcycles are equipped with Hyperpro springs.
