Front Spring XJR1300

【HYPERPRO 22031590 Front Spring XJR1300 Suspension Fork Spring】
■Front Spring
Suspension spring with 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, and also has the ability to maintain stability during 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 gaps during cornering and eliminates vibrations that interfere with the rider.
●Unlike ordinary 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, after completion, each spring undergoes a performance inspection by a tester.
●In the Netherlands, Hyperpro's home country, all emergency motorcycles are equipped with Hyperpro springs.
