Absorbs small bumps during cornering, eliminating vibrations that disturb the rider.\u003cbr\u003e\n ●Unlike regular springs, it does not have a constant spring rate, so it does not resonate.\u003cbr\u003e\n ●Springs are wound by computer-controlled machine tools and then shot-peened to remove microscopic surface imperfections that could lead to performance degradation. Furthermore, after completion, each spring undergoes a performance test by a tester.\u003cbr\u003e\n ●In Hyperpro's home country of the Netherlands, all emergency motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n HONDA X-4 '97-'99\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 1179\u003cbr\u003e\n Fork oil grade\/oil level: SAE10\/195mm\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 Setting remarks: Install with fork protruding 15mm\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.
