Absorbs small bumps during cornering, eliminating vibrations that disturb the rider.\u003cbr\u003e\n ●Unlike ordinary 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 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 YAMAHA FZR600 '89-'93 (3HE)\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 307\u003cbr\u003e\n Fork oil viscosity\/oil level: SAE10\/140mm\u003cbr\u003e\n Preload adjustment: None\u003cbr\u003e\n Sag value: 24mm\u003cbr\u003e\n Compression adjustment: None\u003cbr\u003e\n Rebound adjustment: None\u003cbr\u003e\n Setting remarks: Remove genuine preload bushing\u003cbr\u003e\n *Images are for illustrative purposes only, and the design and specifications of the products shown may change without prior notice.
