has anyone ever had this happen?

Ok Lawrence-

Spouting fancy numbers and letters may get you laid by the ladies but on a bike forum it will get your a$$ kicked....   


JOKING buddy!!

I dont know whether those number and letters were fancy or not but I sure see a bunch of symbols with F and K in them.  I only use those equations when my bike doesn't start!

Recalling that the restoring force F=K*x, where K is the spring "constant" and x is the displacement, in the stock spring the value of K will change much more abruptly than with progressive springs.  In a true progressive, the force/displacement equation will look more like F=K*x^y, where "^" denotes an exponent.  if y=2, for example, the spring follows a square law.  y does not have to be an integer, by the way, and probably isn't for these springs.

Do you mean the value of K will be extremely different between the 2 different springs? (not change more abruptly)  This is interesting, never really got into "spring-math" before.

OK, I see where I have been a bit overbearing, to be kind about it.  Sorry, didn't mean to put anyone down.

What I mean is that the stock spring pictured will have a rather sudden change in "feel" -- from a "soft" spring to a much "harder" one, once the compression reaches the point where the two pitches are pretty close to the same.  This transition will be much more abrupt than in a progressive spring, which will gradually change from "soft" to "hard" as it is compressed.

I did not choose the letters for the equation, by the way -- they are in common use.  Never caught any hidden meaning, but had to laugh when it was pointed out.

I don't think you actually did.  All I was trying to point out for the original poster was that a stock spring can look very much like a progressive and to be sure and compare the two side by side before jumping to the conclusion that it already had progressive springs in it and never really being happy with the way it feels.

I don't think Lawrence was either, I just had to pick on him and this was a great opportunity..
