I've had a clip link on the 650 for about 7K of hard riding, it held up fine. I'm no fan of one type or another, the chain came with that link so I used it. I've had it apart a few times also. The rivited type is definately more secure, given a choice I'd pick that type if it came with the chain I was buying. Ya gotta remember, dirtbikes never had riveted ML for many years, it never stopped anyone from riding the hell out of 'em.
