They certainly improve the roadholding at speed but are not as 'plush' as a good Ohlins setup, but then again Ohlins are more than 2 x expensive
I find the front end is still too harsh at normal road speeds and I am thinking of trying 10wt oil instead of the 15wt supplied in the fork spring kit from Hyperpro. This should allow the spring to compress a little faster/smoother seeing as we have no way of adjusting compression speed mechanically on our bikes.
The return speed (rebound) however is adjustable using a flat screwdriver at the centre of the top fork cap
Veejays settings seem to be something to try out before splashing the cash though, there is nothing to loose as long as you record your current settings BEFORE you start fiddling with anything so you can return to them if not happy
