Absorbs small bumps during cornering, eliminating vibrations that hinder the rider.\u003cbr\u003e\n ●Unlike ordinary springs, there is no constant spring rate, so resonance does not occur.\u003cbr\u003e\n ●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic surface scratches that lead to performance degradation. Furthermore, after completion, each spring undergoes performance testing 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 FZR400RR '90～'93\u003cbr\u003e\n *Images are for illustration purposes only.
