Absorbs small bumps during cornering, eliminating vibrations that disturb the rider.\u003cbr\u003e\n ●Unlike conventional 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 surface scratches that can lead to performance degradation. Furthermore, after completion, each spring undergoes 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 BMW F900XR '20-'22 (without ESA)\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring Part Number: 1821\u003cbr\u003e\n Fork Oil Viscosity\/Oil Level: SAE15\/170mm\u003cbr\u003e\n Preload Adjustment: No adjustment\u003cbr\u003e\n Sag Value: 30-35mm\u003cbr\u003e\n Compression Adjustment: No adjustment\u003cbr\u003e\n Rebound Adjustment: No adjustment\u003cbr\u003e\n Setting Notes: Spring length is 10mm shorter than genuine.
