is there one particular make which is better than the standard one, just seen an evoluzione one at spareshack, but you cant go on looks alone.

I have the one you describe fitted to my Numptystrada and it works perfectly. Having said that I'm sure that there are other brands out there that are equally good

Mike, where is this guy based? do you find the clutch easier to use?

[m1keyp]

The guy is in Germany where they are made, the clutch is significantly improved

Fitted one of Nellys to my 916 last year and would recommend it - it's is much bettter than the standard cylinder.

The problem with aftermarket slaves which claim to reduce lever pressure 30% etc is that the master cyclinder is only still moving the same amount of fluid as when the standard slave was fitted. The reduction in lever pressure is achieved by the slave cylinder having a larger bore which makes the clutch action easier. Conseqently because the fluid volume being moved by the master cylinder is unchanged the piston does not move as far as the standard one which also reduces the travel of the clutch pushrod and so you can have problems with the clutch not disengaging correctly or as smoothly as it should.

So think carefully before going for aftermarket cylinders which claim large reductions of lever pressure.

Nelly claims, sorry if I get the figure wrong Neil, a reduction of about 10% in the lever pressure which is very noticable when riding the bike in traffic etc, when to be honest the standard clutch action is a pain, whilst not being to much to cause any trouble with clutch engamnet/disengagement.

So I support Iconic944ss - go for Nellys every time

Right Mike, and the higher the force-reduction percentage of the slave, the less the clutch pushrod is moved, so the more likely that your clutch will not fully disengage. Usually this causes difficulty moving the selector to neutral because the plates are dragging.

However, you can compensate if you change the 4-position adjustment so that the clutch lever will engage at a point a little farther away from the handlebar. This will increase the fluid stroke volume and move the pushrod more.

The 20% reduction slave like the one from Evoluzione is probably the practical limit here.
