It 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 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 base, all ambulance motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n YAMAHA YZF-R1 '02-'03\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring material number: 1090\u003cbr\u003e\n Fork oil viscosity\/level: SAE7.5\/110mm\u003cbr\u003e\n Preload adjustment: 4-6th stage\u003cbr\u003e\n Sag value: 24mm\u003cbr\u003e\n Compression adjustment: 14-20 clicks out\u003cbr\u003e\n Rebound adjustment: 14 +\/- 4 clicks out\u003cbr\u003e\n Setting notes: Use genuine parts, preload bush L=74mm.
