I just passed 30k on my S2R 800 and I am still running the same clutch.On my old 2003 m800 when the clutch started slipping I could feel and hear the rpm blip up in gear when I tried to accelerate. But that wasnt an ATPC slipper clutch like on my S2R 800.
So my question is does the slipper on my s2r800 will behave the same way as my old bike or not. My M800 clutch blew out after 17k I'm wondering why my S2R clutch has lasted so long. Just wanted to check to see if its supposed to act differently or not.
If it slips it will do the same thing. 30k really isn't lasting all that long for a clutch - most wet-clutch bikes almost never need clutch plates (for example, my TLS which is known for an unusually weak clutch and makes 120hp to the wheel has 60k miles and everything is well within spec).
The APTC clutch will start to slip the same way as your M800 conventional clutch.
It's got a helical spline arrangement so that it pinches the stack tighter under power, and less tight on overrun.
So final question. when I do go to replace? Are there any alternative options than to pay a bazillion dollars for parts from the Ducati Dealer? I love the atpc setup but if there are non dealer markup options that are similar I am willing to consider them.
I couldnt find a lot of topics about replacing wet clutches, so I figured I would ask.
the device it self is what "slips" the plates just sacrafices material as it slips, so you could relally use any plates you want. the question just becomes how long does it last under your type of usage?
For a dry clutch, i stay with OEM plates ,it tsaves me money in the long run and it performs much better than aftermarket alternatives, but it is priced 2x as much. (OEM price is about $330, barrnets are $159).
So..again..what are my options for a wet system.. Dry doesnt matter to me. Are they interchangeable?
Conventional Ducati wet clutch and APTC clutch plates are different.
Stay with OEM plates for wet clutches.

They fit last i remembered. I could be wrong on that.
The only other packs aside from stock OEM are barnetts. Im not too fond of them for dry clutch. I never used them for wet clutch, but installed it for a friend and he had no issues with it YMMV. Barnetts are much cheaper than stock just make sure you get the one based on your model year. I do OEM only for clutch pakcs though.
Ok last 2 questions
Does the clutch basket ever need to be replaced?
Anything else I should check while im in there? I've heard the term throwout bearing mentioned before. Not sure what it is or whether its worth a look.
Baskets on wet clutch bikes hold up very well.
Only one I've replaced was broken by the cover, after it collapsed during a lowside...
Throwout bearing is between the pressure plate and the clutch pushrod.
Again, wet clutch bikes do well, I've not seen one needing to be replaced.
