[QUOTE="hadronuk, post: 42630, member: 1866"] Glen, I think you are right. As I decided fairly quickly to stick with fully sprung, I haven't thought about the original set up so much. Also as you said earlier, the tyre absorbs more with a passenger, because whilst a low unsprung weight is the Holy Grail for roadholding, a higher unsprung weight is actually good for comfort, as it forces the tyre to absorb more road irregularities. Eddy, A bit of lateral thinking! I was only thinking about comfort and spring rates, but now you mention it, I suppose if the proportion of passenger weight carried by the springs rises as the suspension compresses, that is effectively the same as a falling spring rate. I think it is only a small effect though. Incidentally, I think I read somewhere that modern Ducatis have "top out springs" in the forks, so you might have degressive at the front and progressive at the rear! [/QUOTE]
