Front Springs CB400SF CB400SB

【HYPERPRO 22013080 Front Spring CB400SF CB400SB Suspension Fork Spring】
■Front Spring
Suspension springs with a constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes in response to suspension 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 interfere with the rider.
●Unlike regular springs, there is no fixed spring rate, so resonance does not occur.
●Springs wound by computer-controlled machines undergo shot peening to remove microscopic surface scratches that could lead to performance degradation. Furthermore, after completion, each spring undergoes performance testing with a tester.
●In the Netherlands, Hyperpro's home base, all emergency motorcycles are equipped with Hyperpro springs.
