I was just watching this youtube video:

It's really good except it leaves out the part of how the clutch cable actually compresses and decompresses the stack of plates up the center of the clutch.

Presumably the springs shown in the video compress the plates, and that's what you pull against when you pull the clutch in. What's the mechanism that pulls against them? I have a healthy understanding of regular automotive dry clutches, is there simply a throwout bearing in there?

How come I never read about people having throwout bearings dying in their wet clutches? You're actively encouraged to slip clutches on bikes since you won't be able to burn it out, but what about the throwout bearings?
