Front Spring Grom

【HYPERPRO Hyperpro 22017130 Front Spring Grom Suspension Fork Spring】
■Front Spring
Suspension springs 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 grip 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. It absorbs small bumps during cornering, eliminating vibrations that hinder the rider.
●Unlike regular 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 deterioration. Furthermore, after completion, each spring undergoes performance inspection by a tester.
●In the Netherlands, Hyperpro's home country, Hyperpro springs are installed on all emergency motorcycles.
