It absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike ordinary springs, there is no constant spring rate, so there is no resonance.\u003cbr\u003e\n ●Springs wound on a computer-controlled machine are shot-peened to remove microscopic surface scratches that can 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 BMW R80ST '82～'84\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring material number: 2050\u003cbr\u003e\n Fork oil viscosity\/level: SAE10\/120mm\u003cbr\u003e\n Preload adjustment: Not adjustable\u003cbr\u003e\n Compression adjustment: Not adjustable\u003cbr\u003e\n Rebound adjustment: Not adjustable\u003cbr\u003e\n *The image is for illustration purposes only, and the design and specifications of the products shown may change without notice.
