It absorbs small bumps during cornering, eliminating vibrations that disturb the rider.\u003cbr\u003e\n ●Unlike conventional 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 minute surface scratches that lead to performance degradation. Furthermore, after completion, each spring undergoes a performance test by a tester.\u003cbr\u003e\n ●In the Netherlands, where HYPERPRO is based, all emergency motorcycles are equipped with HYPERPRO springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n HARLEY DAVIDSON SOFTAIL '90～'99\u003cbr\u003e\n HARLEY DAVIDSON SOFTAIL FLSTF FAT BOY '90～'99\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring material number: 0382\u003cbr\u003e\n Fork oil viscosity\/oil level: SAE40\/190mm\u003cbr\u003e\n Preload adjustment: None\u003cbr\u003e\n Sag value: 30mm\u003cbr\u003e\n Compression adjustment: None\u003cbr\u003e\n Rebound adjustment: None\u003cbr\u003e\n *The image is for illustrative purposes only, and the design and specifications of the products shown are subject to change without notice.
