Subject: Oberon Slave Cylinder review, (Preliminary.) Sun Mar 31, 2024 5:24 am
Note that this is only a preliminary review and the bike the part was attached to is a huge, steaming, turd.
OK, so first up Michael had to do an air bit of stuffing about to get it to fit and the washers supplied with the kit don't work in this application. That aside the pull is indeed lighter but it is also vague and, at least with the shorty levers on the bike in question, the span adjustment has to be on the furthest out setting to get enough lift for separation and even then there is enough drag to make selecting neutral difficult at a standstill.
Now that may be down to the lever on this bike, it certainly doesn't help, and the clutch has been off at some point and like everything else on the bike may of been the result of butchery on reinstallation. There may also have been bleeding problems, but the pull and feel remains consistent so I think probably not.
All in all, at the moment, I am underwhelmed. But I'll report back after we have re-motored this shitbox it's fitted to and fitted a set of better levers.

I have also fitted one recently along with a new clutch.
I too have short levers which I have adjusted to max span and still have neutral selection issues, but no drag.
I am going to try the OE clutch lever, if not I may swap back to the large piston Moto Guzzi slave and see if the problem goes (as there isn't a great deal of difference in lever pressure between them)
Considered the Oberon slave, but instead went for a Brembo RCS16 master - best choice ever and a lot easier to install. The radial master allows for setting travel and free movement, something unavailable with the stock master cylinder. It is still sensitive to settings and the combination thereof; I played around a lot to find "the" setting that really suited me.
I have swapped the shorty levers for the OE ones, no real difference in operation selecting neutral from 1st is OK but clunks when going from neutral to 1st.
Will put old slave (command) back on and see if that cures all!
