It absorbs minor bumps during cornering, eliminating vibrations that hinder the rider.\u003cbr\u003e\n ●Unlike conventional springs, it does not have a constant spring rate, so it does not resonate.\u003cbr\u003e\n ●Springs wound by computer-controlled machine tools are shot-peened to remove microscopic scratches on the surface that lead to performance deterioration. 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 MV AGUSTA F4S '99-'03 (SHOWA φ49 Fork)\u003cbr\u003e\n Specifications\u003cbr\u003e\n Spring part number: 1297\u003cbr\u003e\n Fork oil grade\/oil level: 2X SAE20\/140mm\u003cbr\u003e\n Preload adjustment: 5th stage\u003cbr\u003e\n Sag value: 22mm\u003cbr\u003e\n Compression adjustment: 2-5 clicks out\u003cbr\u003e\n Rebound adjustment: 8-12 clicks out\u003cbr\u003e\n *Images are for illustration purposes only.
