Hyperpro front fork link system suspension springs
"LINK SYSTEM" SUSPENSION SPRINGS
Hyperpro has put years of extensive Research & Development on front forks, shocks, springs and suspension systems. As most of the time a linear spring is either too hard or too soft at the beginning and/or at the end, a so called one-step progressive spring is an improvement, but is still a compromise between comfort and safety. The sudden change from soft to hard is often felt as a disadvantage and can lead to "speed wobbles". Hyperpro came up with the noncompromising solution: the "Link-System Curve Design" for springs. With this construction a spring can be designed to satisfy all the demands of modern motorcycle technology. Hyperpro gives you a sensitive initial part of the stroke with a smoothly increasing spring rate for safety and anti-dive at the end of the stroke. Together with the use of the highest quality materials and precision machining this results in the best springs that money can buy. The fork springs are manufactured to DIN-2095, class 1 and are specially polished for minimal friction and carry a lifetime warranty against breaking. The shock springs provide superior roadholding & handling under all conditions and are thoroughly tested on a computerized dyno and on the bike in question. They are available with a black or purple polyester surface and the same technical standards as the fork springs. Front fork kits come complete with springs, one liter Hyperpro suspension-fluid, a small tube Hyperpro fork seal lubricant, and a professional manual with suspension tips.Fits 39mm forks
