Absorbs small gaps during cornering and eliminates vibrations that interfere with 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 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 ambulance motorcycles are equipped with Hyperpro springs.\u003cbr\u003e\n Compatible models\u003cbr\u003e\n YAMAHA FJR1300 '01-'08 (ABS not compatible)\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 742\u003cbr\u003e\n Fork oil viscosity\/oil level: SAE20\/200mm\u003cbr\u003e\n Preload adjustment: 2nd stage +\/- 2\u003cbr\u003e\n Sag value: 30mm\u003cbr\u003e\n Compression adjustment: 15 clicks back +\/- 4\u003cbr\u003e\n Rebound adjustment: 4-6 clicks back +\/- 2\u003cbr\u003e\n Setting notes: Assemble with the tapered end down.
