I don't think the older bikes had the ABS option. I may be wrong, but NONE of the used bikes in my area had this option when I was looking. While I would imagine it to be a nice feature, once you learn to get used to it (I've yet to own a bike that has ABS), you can certainly have a ball on these bikes without it!
Good luck with the search.
