Absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike ordinary springs, there is no constant spring rate, so resonance does not occur.\u003cbr\u003e\n ●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.\u003cbr\u003e\n ●In the Netherlands, Hyperpro's home country, all emergency motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n DUCATI MONSTER 900 S4 '01-'03\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring material number: 163\u003cbr\u003e\n Preload adjustment: 17mm (=softest)\u003cbr\u003e\n Sag value: 10mm\u003cbr\u003e\n Compression adjustment: 4.25 turns\u003cbr\u003e\n Rebound adjustment: 18 clicks out\u003cbr\u003e\n *The image is for illustration purposes only, and the design and specifications of the products shown are subject to change without notice.
