Rear Spring ER-4n

【HYPERPRO Hyperpro 22073111 Rear Spring ER-4n Suspension】
■Rear 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, and also provides the resilience needed during high-load cornering and sudden braking.
●Front springs come with the necessary amount of fork oil.
●It optimizes the caster change during braking before a corner, making it easier to transition to the next action. It absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike regular springs, it does not have a constant spring rate, so it does not resonate.
●Springs are wound on computer-controlled machines and then shot-peened to remove microscopic surface scratches that can lead to performance degradation. Furthermore, after completion, each spring undergoes performance inspection by a tester.
●In Hyperpro's home country of the Netherlands, all emergency motorcycles are equipped with Hyperpro springs.
