I've got a little over 3k on my 2003 R6 and when brand new, my clutch would grab when the lever was not quite half way let out - now it grabs just a hair before its all the way out. I've checked the cable for slack both at the lever and at the engine case, played with tightening or loosening it, and I have the right slack according to spec meaning that the cable has only stretched a tiny bit, if at all, over that 3k of miles.
My riding is mostly stop and go in the city, or maybe more like stop and race to the next light and then stop again.
So whats the normal lifespan for stock clutch plates?
