Front spring XB12R XB9R

【HYPERPRO 22091400 Front Spring for XB12R XB9R 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.
This maintains a state that is neither too soft nor too hard, and also provides the strength to endure high-load cornering and sudden braking.
●Optimizes the caster change 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 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 test by a tester.
●In the Netherlands, Hyperpro's home country, all emergency motorcycles are equipped with Hyperpro springs.
