It absorbs minor gaps 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 base, all ambulance motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n YAMAHA FZ400 '97-'99\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring Part Number: 402\u003cbr\u003e\n Fork Oil Viscosity\/Oil Level: SAE15\/140mm\u003cbr\u003e\n Preload Adjustment: No adjustment\u003cbr\u003e\n Sag Value: 25mm\u003cbr\u003e\n Compression Adjustment: No adjustment\u003cbr\u003e\n Rebound Adjustment: No adjustment\u003cbr\u003e\n Setting Remarks: Install with fork protruded by 15mm\u003cbr\u003e\n *The image is for illustrative purposes only, and the design and specifications of the products shown may change without prior notice.
