yeah my bike had 28mm of pushrod extended from the casing which is right on the edge of what oberon say to use the spacer on. SHouldn't have needed it though on an 848. But yeah, haven't been able to get it to function with either the spacer in or out. Either disengages always or doesn't disengage at all. I'm definitely pushing the piston full back before fitting too. Well let's just say my bike has a chequered past, so I'll assume it's something odd about the bike or the guy holding the spanners since everyone elses is working ok Back to old slave cylinder for me and it's running fine.
I put a brembo adjustable master cylinder on my 848; also makes the clutch action lighter. Best not to do this and the oberon at the same time as removing tension at both ends makes for a temperamental clutch that sometimes fails to disengage. Either option recommended; just not both at the same time. 959 clutch is bang-on standard
On each of my 2011 and 2015 Multistradas the standard clutch slave gave problems after 10 or 20 thousand miles (leaking, sticking, bleeding air) so each time I fitted an Oberon. Worked well, solved problems. So when I bought my 2017 Multi, I got Snells to fit an Oberon from new. The standard part would probably give trouble sooner or later, I thought, so best to pre-empt the problems at the outset. Incidentally I notice that the 1260 Multi has an entirely different clutch slave. Presumably it is intended to deal with the long standing complaints. If anyone has put mileage on a 1260, I would be interested to hear how the clutch is doing. Amongst other things of course.
Put an Oberon slave cyl on my 916 earlier this year. Made no difference at all. Lever pull effort is still on the heavy side. But the old one will go on my 900 to replace the '94 original which suffers seal failures now and then. Wouldn't buy another Oberon unless it was cheaper than the alternatives.
£92 on a carbon trinket no one looks at or an improved slave that makes the bike more of a joy to ride...toughie I'm with you on that one.
Have a go on a bevel twin clutch lever and then quit moaning you big jessies... 749 had a standard slave... was fine 999 has an Oberon... it's fine, but is gold and offends me greatly with its goldness. 748 had standard slave... was fine 900 SL has standard slave... is fine 900 SS had standard slave, swapped it for an RSR Moto one... slightly lighter clutch and is as good as the Oberon (talk to @richgilb about RSR Moto if interested. "He the man", as the kids say). That's my experience. Perhaps on 848 / 1098 / 1198 / 899 / 959 / 1199 / 1299 the difference is more pronounced. I'll likely put a grey / silver Oberon on the 999 when I get upset enough. Or an RSR Moto one as they're cheaper and look pretty much as good.
Cheers, shameless plug on the silver ones. I ended up with 30 by accident. So they are even cheaper until I clear a few! https://rsrmoto-europe.com/collecti...99-1098-monster-hyper-streetfighter-diavel-si
But do they reduce the effort needed to use the clutch or are they the same operationaly as a standard one - just with extra silver shine?
Definitely lighter. The piston is 30mm wide vs 25mm on OEM (or was it 26...can't remember). Physics calculations here! https://www.ducati.ms/forums/80-hal...ter-market-clutch-master-slave-cylinders.html
I believe you can buy an Oberon with the same size cylinder and piston as oem. If you had one of these as opposed to a larger bore size, then it will indeed feel exactly the same. If you have one with a larger bore than oem it should feel lighter but at the expense of a longer throw at the lever/shorter throw at the pushrod, as has been said.
Done. to replace horrible 'red' version fitted by PO. For some reason the website appears to think I'm German...
Old Rider - as you say, I must have bought one the same size as the original. As for being a Jessie Mr Fire, I had a 1980 GSX11 with heavy duty everything on it for several years so Ducati clutches were once soft and easy for me. 24 years later, and having been rapped on the knuckles by a ZZR1100 in a head-on incident in 1995 means my left hand is not so strong these days.
AH yes, but there's Ducati clutches and Ducati bevel clutches. No comparison. I've seen one or two hydraulic conversion kits for the latter but they are either hugely expensive (Bevelheaven) or a little crude (but effective). There was a retired engineer in the Owners Club recently looking to develop a discrete adaptor for a standard slave cylinder, was hoping to do it for under £100 - but not enough interest to make it worthwhile. I'd def had one as I've become something of a jessie over the years... Busted knuckles sound painful
