It absorbs small bumps during cornering, eliminating vibrations that hinder 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 minute 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 KAWASAKI ZEPHYR400 '89-'95\u003cbr\u003e\n KAWASAKI ZEPHYR400X '96\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring Part Number: 229\u003cbr\u003e\n Fork Oil Grade\/Oil Level: SAE20\/140mm\u003cbr\u003e\n Sag Value: 25mm\u003cbr\u003e\n Setting Notes: 12mm protrusion\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the products shown are subject to change without notice.
