I’m pretty sure most of us would never be able to tell the difference between the 540 and 640 if we did a blindfold test. For the type of riding I do, I would not have gone for the 643 competition shock.
For me, preload & rebound (especially rebound on the Bobber) always nice to play with once in a while just to fine tune the handling. But again, that kind of tinkering is only for those who enjoy doing it; otherwise the 540 will function and do the job just as well as the 640 (IMHO).
*just to state: I have not touched the preload once since receiving my 640.
Wilbers make fantastic quality shocks and once I felt how it improved my Bobber I ordered a full set for my GSA, which was also totally transformed (even more so than the Bobber!)
