Absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike ordinary 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 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 S4R '04-'07\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring material number: 1085\u003cbr\u003e\n Fork oil grade\/oil level: SAE10\/120mm\u003cbr\u003e\n Preload adjustment: 1st-3rd stage\u003cbr\u003e\n Sag value: 24mm\u003cbr\u003e\n Compression adjustment: 0.25 turns out\u003cbr\u003e\n Rebound adjustment: 10 clicks (+\/-3)\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.
