Absorbs small gaps during cornering and eliminates vibrations that would 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 can 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 YAMAHA YZF-R1 (ABS) '15-'19\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring Part Number: 1144\u003cbr\u003e\n Fork Oil Grade\/Oil Level: SAE7.5\/150mm\u003cbr\u003e\n Preload Adjustment: 6.75 turns\u003cbr\u003e\n Sag Value: 24mm\u003cbr\u003e\n Compression Adjustment: 22 clicks\u003cbr\u003e\n Rebound Adjustment: 15 clicks\u003cbr\u003e\n Setting Remarks: Protrusion amount 10mm \/ Spring is 10mm longer than genuine.\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.
