It absorbs small bumps during cornering, eliminating vibrations that disturb the rider.\u003cbr\u003e\n ●Unlike conventional springs, it does not have a fixed spring rate, so it does not resonate.\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 a performance inspection by a tester.\u003cbr\u003e\n ●In the Netherlands, Hyperpro's home country, Hyperpro springs are installed on all emergency motorcycles.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n SUZUKI GSX-R750 '90-'91 (Export specification \/ Inverted fork φ41)\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 39\u003cbr\u003e\n Fork oil viscosity\/oil level: SAE7.5\/100mm\u003cbr\u003e\n Preload adjustment: R=4\u003cbr\u003e\n Sag value: 24mm\u003cbr\u003e\n Compression adjustment: 1 turn\u003cbr\u003e\n Rebound adjustment: 1 turn\u003cbr\u003e\n Setting remarks: Install with fork extended 18mm (stock=13mm)\u003cbr\u003e\n *Images are for illustration purposes only.
