It 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 scratches on the surface that lead to performance degradation. Furthermore, after completion, each spring undergoes a 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 HONDA CBR400RR '90-'93\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring material number: 402\u003cbr\u003e\n Fork oil viscosity\/oil level: SAE20\/130mm\u003cbr\u003e\n Preload adjustment: 3-5 clicks\u003cbr\u003e\n Sag value: 20mm\u003cbr\u003e\n Compression adjustment: None\u003cbr\u003e\n Rebound adjustment: None\u003cbr\u003e\n Setting notes: Uses genuine preload bush (L=150mm)\u003cbr\u003e\n *The image is for illustration purposes only, and the design and specifications of the products shown are subject to change without notice.
