Absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike regular springs, it does not have a constant spring rate, so it does not resonate.\u003cbr\u003e\n ●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 a performance inspection using a tester.\u003cbr\u003e\n ●In the Netherlands, Hyperpro's home base, all emergency motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n HARLEY DAVIDSON SPORTSTER XL1200N NIGHTSTER '08～'13\u003cbr\u003e\n HARLEY DAVIDSON SPORTSTER XL883N IRON '09～'13\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring Part Number: 1299\u003cbr\u003e\n Fork Oil Viscosity\/Oil Level: SAE15\/100mm\u003cbr\u003e\n Preload Adjustment: Not adjustable\u003cbr\u003e\n Sag Value: 20mm\u003cbr\u003e\n Compression Adjustment: Not adjustable\u003cbr\u003e\n Rebound Adjustment: Not adjustable\u003cbr\u003e\n Setting Notes: Spring is 45mm shorter than stock \/ Uses stock preload bush (200mm)\u003cbr\u003e\n *Images are for illustration purposes only.
