Absorbs small bumps during cornering, eliminating vibrations that interfere with the rider.\u003cbr\u003e\n ●Unlike regular springs, there is no constant spring rate, so there is no resonance.\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 HONDA CBX550F '82-'85 (F2 compatible)\u003cbr\u003e\n HONDA CBX400F '82-'85\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 2057\u003cbr\u003e\n Fork oil grade\/oil level: SAE10\/150mm\u003cbr\u003e\n Preload adjustment: No adjustment\u003cbr\u003e\n Compression adjustment: No adjustment\u003cbr\u003e\n Rebound adjustment: No adjustment\u003cbr\u003e\n Setting notes: Remove both types of genuine springs before installation.\u003cbr\u003e\n *Images are for illustration purposes only.
