It absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike regular 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 a performance test by a tester.\u003cbr\u003e\n ●In Hyperpro's home country of the Netherlands, all ambulance motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n KAWASAKI Z400 '19-'20\u003cbr\u003e\n KAWASAKI Z250 ABS '19-'21\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 1801\u003cbr\u003e\n Fork oil viscosity\/level: SAE15\/140mm\u003cbr\u003e\n Preload adjustment: Not adjustable\u003cbr\u003e\n Sag value: 24mm\u003cbr\u003e\n Compression adjustment: Not adjustable\u003cbr\u003e\n Rebound adjustment: Not adjustable\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the products shown may change without notice.
