Absorbs small gaps during cornering, eliminating vibrations that interfere with 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 lead to performance degradation. Furthermore, after completion, each spring undergoes performance testing 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 INDIAN CHIEFTAIN '15-'21 (pressurized shock)\u003cbr\u003e\n INDIAN ROADMASTER '15-'21 (pressurized shock)\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 1727\u003cbr\u003e\n Fork oil viscosity\/level: 2X SAE20\/160mm\u003cbr\u003e\n Preload adjustment: No adjustment\u003cbr\u003e\n Sag value: 24mm\u003cbr\u003e\n Compression adjustment: No adjustment\u003cbr\u003e\n Rebound adjustment: No adjustment\u003cbr\u003e\n Setting remarks: Spring is 20mm shorter than genuine\/Install with the tapered end facing down\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the products shown may change without notice.
