Rear Spring WR250F

【HYPERPRO Hyperpro 22035071 Rear Spring WR250F 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 has the ability to withstand high-load cornering and sudden braking.
●Front springs come with the necessary amount of fork oil.
●It optimizes the change in caster during braking before a corner, making it easier to transition to the next action. It absorbs small gaps during cornering and eliminates vibrations that interfere with the rider.
●Unlike regular springs, there is no 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 base, all emergency motorcycles are equipped with Hyperpro springs.
