It absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike regular springs, there is no 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 lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection by a tester.\u003cbr\u003e\n ●In the Netherlands, Hyperpro's home country, all ambulance motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n KAWASAKI ZX-9R '99\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring Part Number: 742\u003cbr\u003e\n Fork Oil Viscosity\/Oil Level: SAE15\/130mm\u003cbr\u003e\n Preload Adjustment: 4th step\u003cbr\u003e\n Sag Value: 24mm\u003cbr\u003e\n Compression Adjustment: 12 clicks out\u003cbr\u003e\n Rebound Adjustment: 3-5 clicks out\u003cbr\u003e\n *Images are for illustration purposes only.
