That's odd that the handbook says 8 rings. The service manual says 5 rings is fully out, standard position 2... they look fully out to me and although my memory is a bit hazy, I don't remember ever seeing all 5 rings. Looks normal, in other words.
Judging by the forks sitting a few mm high, it looks like the previous owner has made adjustments, so there might be stiffer springs or a upgrade kit in there too. You won't know unless you take them apart, of course.
