Hi all, I have just imported two of these - one will be going on my bike, the other will be going on eBay... Evoluzione Ducati OEM Slave Cylinder Piston Replacement (90050) | Pro Italia My slave seal blew just before Xmas, I have fitted a new seal but in the meantime also rebuilt/repainted my engine. Eventually the new seal will cook itself, leak brake fluid all down my case & leave me stranded. This does not strike me as a fun thing to happen. Rather than wait for this to happen I will be fitting the above, which looks to have a belt-&-braces double seal to it? Winwin. Watch this space.
