I am going to say no, they will not fit. I have Roll pegs on both my 450R and 700XX. The bolt holes may be the same pattern, but the 450R pegs the bolts are at a slight angle (rear bolt a little higher then the front) while the 700XX the bolts are at the same height. The 450R pegs may bolt up, but they will not be level. If my 700 was in the gargage I would confirm, but it is not, but I am 95% sure this is what I remember.
