Absorbs small bumps during cornering, eliminating vibrations that disturb the rider.\u003cbr\u003e\n ●Unlike conventional springs, they do not have a constant spring rate, so they do not resonate.\u003cbr\u003e\n ●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic surface scratches that could 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 ambulance motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n YAMAHA BT1100 BULLDOG '01-'07\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring material number: 240\u003cbr\u003e\n Fork oil viscosity\/oil level: SAE10\/170mm\u003cbr\u003e\n Preload adjustment: 6-7th stage\u003cbr\u003e\n Sag value: 24mm\u003cbr\u003e\n Compression adjustment: None\u003cbr\u003e\n Rebound adjustment: None\u003cbr\u003e\n Setting notes: Use genuine bush 150mm.
