Message: [QUOTE="canyncarvr, post: 633966, member: 16552"] Well...if you found those posts, you probably came across some of the reasons? Basically, the point of the fork is suspension, isn't it? Then why fill it with almost 4" of steel (the oem spacer)? A spring does not compress in a linear fashion. The more it is compressed, the faster the rate changes. A longer spring can be compressed further and retain its stated rate. I've heard argument regarding motion transfer time..that a shorter spring transmits motion faster, and that speed is good. OK. The difference of that in the real world between a 470mm and a 530mm spring is likely zip. I've heard the argument of weight difference, the spring being an unsprung component...and unsprung weight is a bad thing. I need to weigh an oem spring and compare it to one of my XR springs...but I'll bet it's next to nothing difference wise. So, back to the world of real. I rode two kdxs modified exactly the same with the exception of one with XR springs, one with eibach (470mm) springs. Huge difference. Huge enough that from one ride to the next on my bike with the .40 eibach 470mm springs changed to the .40 honda 530mm springs, the difference was [b]still[/b] huge. No question but that the longer spring performed better. The fact that oem springs are generally hot-wound, and aftermarket springs are cold-wound is a plus. Failure rate of cold-wound springs isn't huge, but it happens. It happened to me, actually. A brand new set of .42s failed with one spring getting 10mm shorter than the other over the span of several rides. That's BS. There are reasons to use longer spacers. Where the fork rides in the stroke is important for proper suspension. That's where the sag measurement comes in. If you have to use 4" of spacer to get the sag in the ballpark, I'd say you need a different spring in the first place. [/QUOTE]
