Absorbs small bumps during cornering, eliminating vibrations that hinder the rider.\u003cbr\u003e\n ●Unlike conventional 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 scratches on the surface that can lead to performance degradation. Furthermore, each spring undergoes a performance inspection by a tester after completion.\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 ST4 '99-'03\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 0523\u003cbr\u003e\n Fork oil viscosity\/oil level: SAE5\/120mm\u003cbr\u003e\n Preload adjustment: 4th stage\u003cbr\u003e\n Sag value: 23mm\u003cbr\u003e\n Compression adjustment: None\u003cbr\u003e\n Rebound adjustment: 12 (+\/-2) clicks\u003cbr\u003e\n *Images are for illustration purposes only.
