‘Original’ Progressive Rate Fork 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.
rates of these progressively wound springs have been
carefully designed to fit each model. Spring rates have
been chosen to reduce front end “dive” under braking yet
still provide excellent ride comfort. In addition, we
warranty our fork springs for life!
Progressive Rate Fork 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.
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
