It absorbs small gaps during cornering, eliminating vibrations that would interfere with the rider.\u003cbr\u003e\n ●Unlike conventional 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 could lead to performance degradation. Furthermore, each finished spring undergoes a performance inspection with 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 HONDA CB400SF '98~'03 (V-TEC1, 2)\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 1040\u003cbr\u003e\n Fork oil grade\/level: SAE10\/160mm\u003cbr\u003e\n Preload adjustment: Not adjustable\u003cbr\u003e\n Sag value: 28mm\u003cbr\u003e\n Compression adjustment: Not adjustable\u003cbr\u003e\n Rebound adjustment: Not adjustable\u003cbr\u003e\n Setting notes: Uses genuine preload bush (194mm\/SPEC1, 200mm\/SPEC2)\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the products shown are subject to change without notice.
