Absorbs fine bumps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike regular springs, there is no constant spring rate, so resonance does not occur.\u003cbr\u003e\n ●Springs wound on computer-controlled machine tools are shot-peened to remove microscopic surface scratches that can lead to performance degradation. Furthermore, after completion, each 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 '07-'08\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 549\u003cbr\u003e\n Preload adjustment: POS 4-6\u003cbr\u003e\n Sag value: 10mm\u003cbr\u003e\n Compression adjustment: High-speed 2.5 turns \/ Low-speed 10 clicks\u003cbr\u003e\n Rebound adjustment: 7 clicks +\/- 2 clicks back\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the products shown may change without prior notice.
