Front fork springs CB400SF

【HYPERPRO Hyperpro 22013130 Front Spring CB400SF 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 the caster change during braking before a corner, making it easier to transition to the next action. It absorbs minor bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike conventional springs, it does not have a constant spring rate, so it does not resonate.
●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic scratches on the surface that lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection using a tester.
●In the Netherlands, Hyperpro's home country, Hyperpro springs are installed on all emergency motorcycles.
