It absorbs small gaps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike regular springs, there is no fixed 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 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 ZZR400 '93～'94\u003cbr\u003e\n KAWASAKI ZZR600 '93～'94\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 144\u003cbr\u003e\n Fork oil viscosity\/oil level: SAE7.5\/130mm\u003cbr\u003e\n Preload adjustment: No adjustment\u003cbr\u003e\n Sag value: 24mm\u003cbr\u003e\n Compression adjustment: No adjustment\u003cbr\u003e\n Rebound adjustment: No adjustment\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the products shown are subject to change without prior notice.
