[QUOTE="Fred W, post: 1286333, member: 3828"] Yeah, we've had this discussion before. Suppose that the FJR1300 did not have top out springs. If that were the case then these would qualify as preload adjusters in your definition because the main spring would be compressed at full length, right? How would it change how these adjusters affect the way the suspension rides? It would be completely identical to how it works now. Right up to the point where the suspension tops out, which it really never should anyways. Besides, it takes some amount of force to compress those top out springs, so in actuality as the top out springs are compressing (and fork lengthening) the main spring is being compressed somewhat as it delivers the added force to the top out springs. I really do not see what the difference is that the fork elongates because of a top out spring compressing or not. The effect of screwing in the adjuster is [I]exactly the same[/I] as adding additional spacer distance above the spring: it raises the loaded suspension's ride height [I]and that is all. [/I]That is all that spring preload [I]ever does [/I]whether there is a hard top out or a spring buffered one. [/QUOTE]
