Combination Kit Front & Rear Springs Sportster XL1200N XL883N

【HYPERPRO Hyperpro 22091812 Combi Kit Front & Rear Spring Sportster XL1200N XL883N Suspension】
■Combi Kit
Suspension springs with constant rising rates uniquely designed by Hyperpro.
The spring rate constantly changes in response to suspension movement.
This maintains a state that is neither too soft nor too hard, and also provides the resilience needed during high-load cornering and sudden braking.
●The front spring comes 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. Absorbs small bumps during cornering, eliminating vibrations that disturb the rider.
●Unlike conventional springs, there is no constant spring rate, so resonance does not occur.
●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 performance inspection by a tester.
●In Hyperpro's home country of the Netherlands, all emergency motorcycles are equipped with Hyperpro springs.
