Absorbs small bumps during cornering, eliminating vibrations that interfere with 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 base, Hyperpro springs are installed on all emergency motorcycles.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n SUZUKI DR-Z400SM '05～'09\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 1038\u003cbr\u003e\n Fork oil grade\/oil level: SAE7.5\/375cc\u003cbr\u003e\n Preload adjustment: No adjustment\u003cbr\u003e\n Sag value: 35mm\u003cbr\u003e\n Compression adjustment: 15 clicks back\u003cbr\u003e\n Rebound adjustment: 5-7 clicks back\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the products shown may change without prior notice.
