I have all forks and yokes already off of a yzf

I'm not sure what your asking? Will they fit what?
If your asking will R1 forks fit fzs600 yokes the answer is no
Your also need the spindle, spacers front, fender etc...
I would be looking for a compleat front end not just forks
Don't forget with the R1 front end the fzs spindle is thinner so your need to get it adapted
