{"product_id":"ac-22093620","title":"Front Spring Dyna FXDF","description":"[HYPERPRO 22093620 Front Spring Dyna FXDF Suspension Fork Spring]\n■Front Spring\nSuspension springs with a constant rising rate, uniquely designed by Hyperpro.\nThe spring rate constantly changes in response to the suspension's movement.\nIt maintains a state that is neither too soft nor too hard, and also has the ability to maintain stability during high-load cornering and sudden braking.\n●Optimizes changes in caster during braking before a corner, making it easier to transition to the next action. It absorbs small gaps during cornering and eliminates vibrations that interfere with the rider.\n●Unlike ordinary springs, there is no constant spring rate, so there is no resonance.\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 inspection by a tester.\n●In the Netherlands, Hyperpro's home base, all emergency motorcycles are equipped with Hyperpro springs.\nCompatible models\nHARLEY DAVIDSON DYNA FXDF FAT BOB '08~'09\nSpecifications\nSpring part number: 1490\nFork oil viscosity\/oil level: SAE20\/160mm\nPreload adjustment: No adjustment\nSag value: 20mm\nCompression adjustment: No adjustment\nRebound adjustment: No adjustment\nSetting notes: Spring is 30mm shorter than genuine\/Please use the genuine 200mm spacer\n*The image is for illustrative purposes only, and the design and specifications of the products shown may change without notice.
