Hi Folks,  Just a heads up.  I had purchased a Ducabike slave cylinder for my 2013 M1100 and it did not fit, not at all.  I sent the pics I put up in a different thread to Jeff at Monster Parts and he was quite surprised.  He then sent the pics off to Ducabike. 

I did not get the wrong slave, I got the one they think fits a 2013......  The Oberon dropped right in though.

Other than looks does the aftermarket slave cylinder do anything?  It's not like the Evo has a hard clutch like the dry clutch models. 

It seems to reduce the lever effort a bit.  Especially nice in traffic.  Oh and it looks freaking sweet!  Pics later ( :
