It absorbs small bumps during cornering, eliminating vibrations that would hinder the rider.\u003cbr\u003e\n ●Unlike ordinary 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 surface scratches that can lead to performance degradation. Furthermore, after completion, each spring undergoes a performance inspection by a tester.\u003cbr\u003e\n ●In the Netherlands, where Hyperpro is headquartered, all emergency motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n YAMAHA SEROW250 '05～'21\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 1658\u003cbr\u003e\n Fork oil viscosity\/level: SAE20\/150mm\u003cbr\u003e\n Preload adjustment: No adjustment\u003cbr\u003e\n Sag value: 35mm\u003cbr\u003e\n Compression adjustment: No adjustment\u003cbr\u003e\n Rebound adjustment: No adjustment\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.
