Absorbs small gaps during cornering and eliminates vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike ordinary springs, there is no constant spring rate, so resonance does not occur.\u003cbr\u003e\n ●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic scratches on the surface that lead to performance degradation. Furthermore, after completion, each spring undergoes performance inspection by a tester.\u003cbr\u003e\n ●In Hyperpro's home country of the Netherlands, all emergency motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n BUELL S3 '99-'00\u003cbr\u003e\n BUELL X1 '99-'00\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring material part number: 0603\u003cbr\u003e\n Fork oil grade\/oil level: SAE10\/140mm\u003cbr\u003e\n Preload adjustment: No adjustment\u003cbr\u003e\n Sag value: 25mm\u003cbr\u003e\n Compression adjustment: Weakest\u003cbr\u003e\n Rebound adjustment: 1 turn back (+\/- 0.5)\u003cbr\u003e\n *The image is for illustrative purposes only, and the design and specifications of the products shown may change without prior notice.
