Front Springs Chieftain Roadmaster

【HYPERPRO Hyperpro 22094590 Front Spring Chieftain Roadmaster Suspension Fork Spring】
■Front Spring
Suspension springs with a constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes to follow 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. Absorbs small gaps 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 performance testing by a tester.
●In the Netherlands, Hyperpro's home country, all emergency motorcycles are equipped with Hyperpro springs.
