Rear Spring WR250F

[HYPERPRO Hyperpro 22035061 Rear Spring WR250F Suspension]
■Rear Spring
Suspension spring 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 maintain stability during high-load cornering and sudden braking.
●Front springs come with the necessary amount of fork oil.
●Optimizes the change 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 ordinary 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 surface scratches that can lead to performance degradation. Furthermore, after completion, each spring undergoes a performance test by a tester.
●In the Netherlands, Hyperpro's home country, all emergency motorcycles are equipped with Hyperpro springs.
