[Hyperpro 22094941 Rear Spring Sportster S Suspension Motorcycle Parts Active]
■Product Description 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 power to withstand 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 interfere with the rider. ●Unlike ordinary springs, there is no constant spring rate, so there is no resonance. ●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic surface scratches that 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. ■Compatible models HarleyDavidson/Harley-Davidson SPORTSTER S (RH1250S) 2022 ■Specifications Spring part number: 163 Preload adjustment: HPA weakest Compression adjustment: 2・1/4 turns back Rebound adjustment: 1・1/2 turns back ■Notes *Images are for illustration purposes only.
