It absorbs minor bumps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike regular springs, there is no fixed spring rate, so resonance does not occur.\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 a performance inspection by 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 YAMAHA FZR1000 '89-'90 (EXUP)\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 304\u003cbr\u003e\n Fork oil viscosity\/oil level: SAE15\/150mm\u003cbr\u003e\n Preload adjustment: 1st stage\u003cbr\u003e\n Sag value: 18mm\u003cbr\u003e\n Compression adjustment: None\u003cbr\u003e\n Rebound adjustment: None\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the products shown are subject to change without notice.
