Combi Kit Front & Rear Springs XJR400 XJR400S

[HYPERPRO 22033012 Combi Kit Front & Rear Spring for XJR400 XJR400S Suspension]
■Combi Kit
Suspension springs with constant rising rate, uniquely designed by Hyperpro.
The spring rate constantly changes in response to suspension movement.
It maintains a state that is neither too soft nor too hard, while also providing the resilience needed during high-load cornering and sudden braking.
●The front spring comes 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 minor bumps during cornering, eliminating vibrations that interfere with the rider.
●Unlike ordinary springs, it does not have a constant spring rate, so there is no resonance.
●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic surface scratches that could lead to performance degradation. Furthermore, after completion, each spring undergoes performance inspection by a tester.
●In Hyperpro's home country of the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.
