Proven extensively in desert, woods, Baja and I.S.D.E. competitions, Progressive Suspension Springs offer superior handling characteristics throughout your suspension's complete travel cycle and increases the overall bottoming resistance as well. When used in conjunction with proper shock and fork valving, the Progressive Suspension Springs will transform your suspension into a superior handling machine. Precision construction and high quality materials enable us to warranty this spring for as long as you own it! Progressive Springs are designed to be softer in their initial movement to keep a comfortable and responsive ride over the rocks, roots, ruts and logs. They offer a higher bottoming resistance to help manage high the results of speed impacts! These springs are guaranteed not to break, forever! The Progressive Rate Springs soak up the small road bumps yet are firm enough to absorb the larger ones. The progressively wound design gives you the best of both worlds. When you install these fork springs you'll be amazed at the improvement you'll feel in the handling and ride of your motorcycle. The rates of these progressively wound springs have been carefully designed and rigorously tested to fit each specific make and model motorcycle. Spring rates have been chosen to reduce front end dive under braking yet still provide excellent ride comfort. Additionly, Progressive Suspension warranties springs for life! Progressive Rate Springs have many advantages over straight rate springs. A straight rate spring only offers linear resistance to compression and is a compromise. For example, if you have a 20lb. straight rate spring it will take 20lbs. of force to compress the spring one inch. Then, it will take 20 more lbs. of force to compress it the next inch, and so on, until the end of the travel. A Progressive Rate Spring has the advantage of a rising rate resistance to compression. For example, a 15lb. to 25lb. Progressive Rate Spring will take 15lbs. to compress it the first inch, then 17lbs. the next inch, and so on, until the end of the travel; it will take an additional 25lbs. to compress it the last inch. The benefit of this is that the spring can be soft enough at the start of the travel to offer a plush ride yet be firm enough at the end of the travel to soak up the big bumps.
