Absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike ordinary 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 surface scratches that can lead to performance degradation. Furthermore, after completion, each spring undergoes a performance test 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 KTM 620-E DUKE '94-'97\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring Part Number: 0390\u003cbr\u003e\n Fork Oil Weight\/Oil Level: SAE15\/140mm\u003cbr\u003e\n Preload Adjustment: No adjustment\u003cbr\u003e\n Sag Value: 30mm\u003cbr\u003e\n Compression Adjustment: Weakest\u003cbr\u003e\n Rebound Adjustment: Strongest\u003cbr\u003e\n Setting Notes: Remove genuine washer (10mm)\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the products shown are subject to change without notice.
