Absorbs small bumps during cornering, eliminating vibrations that interfere with 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, each finished spring undergoes a performance inspection by a tester.\u003cbr\u003e\n ●In Hyperpro's home country of the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n YAMAHA YZF-R1 '04-'06\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring Part Number: 862\u003cbr\u003e\n Fork Oil Viscosity\/Oil Level: SAE10\/120mm\u003cbr\u003e\n Preload Adjustment: 4-5th stage\u003cbr\u003e\n Sag Value: 23mm\u003cbr\u003e\n Compression Adjustment: 25 +\/- 5 clicks out\u003cbr\u003e\n Rebound Adjustment: 17 +\/- 4 clicks out\u003cbr\u003e\n Setting Notes: Use genuine parts, preload bush L=100mm.
