Great question! Happy to share my early impressions. Mind you I have zero suspension sophistication or point of reference. If we could ride well set up stock, S100RR, Wilbers and Ohlins side by side, in succession I'd know something. But I a coming from a very basic non-adjustable stock fork with 6k of easy miles on the original BMW 7.5w fluid and comparing to a slightly upgraded similar model with three times the adjustability and brand new BMW 11.5w fluid (albeit it's probably the same practical viscosity as I believe the difference is based on a mfg change). Add to that that I am no lightweight at 250#+ so that factors into any discussion of 'performance'.
First impressions are noted in post #99 just above yours. Since that the forks have loosenes a bit and thay have been worked. I am breaking in a new front tire at the same time so some more aggressive behavior has been delayed. BUt after playing a bit with the preload and two damping adjustments I do believe that A) they are far better suited to my weight than the otriginals and B) the general front end related ride is noticeably improved with less hard edged jarring from that end of things. It does seem to roll things like frost humps and bridge joints a lot better than stock and I find them more comfortable overall. Thhet are stiffer in most situations, whether just manually bouncing the front end in the darage to test to less diving in harder breaking. There is stii more to be learned once the front tire is fully able to throw in to cornering I'll know if that's better. The stock felt a tad wallowy to me. But I never hated the stock and could have coexisted with them just fine. But I believe the S1000RR are just better in every way because of their adjustability. I'd also think that an Ohlins or Wilbers would be markedly better than these in teh same way as a lot of S1000RR owners scrap these for those pretty quickly. But fro my casual riding I'd expect these will suit me moe than fine at a quarter to third of those two brands. I can live with that.
