Absorbs small bumps during cornering, eliminating vibrations that disturb the rider.\u003cbr\u003e\n ●Unlike conventional 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 scratches on the surface 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 HONDA CB900F '81 (FB\/Fork φ37)\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring Part Number: 2052\u003cbr\u003e\n Fork Oil Viscosity\/Oil Level: SAE15\/140mm\u003cbr\u003e\n Preload Adjustment: None\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 may change without prior notice.
