It absorbs small gaps during cornering, eliminating vibrations that disturb the rider.\u003cbr\u003e\n ●Unlike ordinary springs, there is no constant spring rate, so there is no resonance.\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 a 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 YAMAHA XJ900 DIVERSION '96-'08\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring Part Number: 491\u003cbr\u003e\n Fork Oil Viscosity\/Oil Level: SAE15\/140mm\u003cbr\u003e\n Preload Adjustment: 4th stage\u003cbr\u003e\n Sag Value: 27mm\u003cbr\u003e\n Compression Adjustment: None\u003cbr\u003e\n Rebound Adjustment: None\u003cbr\u003e\n Setting Notes: Remove the genuine spacer (L=150mm)\u003cbr\u003e\n *The image is for illustrative purposes only, and the design and specifications of the products shown are subject to change without notice.
