lets put it this way to put 400ex a arms on a 250r it requires a 1/4" spacer to allow it to be mounted.

Yes they will fit, but they need to be machined to fit.

If you have any machining skills or know someone who does it is an easy mod. You just have to cut a bit off where the arms mount to the frame.

They have hiem joints where it attaches to the frame tho, will they still not fit

then you'll have to machine the spacers to fit.
