Once sorted, mine was then fine for 4 years but is currently off as I've fitted Givi pannier rails (which are built around a standard rear fender/mudguard set-up).
I keep saying I need to work out whether I can "sympathetically modify" the Ermax to take the Givi rail bracketry at the same time...
I still have the Ermax on my Gladius, and I still think it is the best looking tail tidy I've seen for a Gladius.
In my experience almost all changes made to a Gladius require 'some' fettling! In some cases, a lot! I think the Ermax tops that list though.
