Lorin, This really is a straight forward swap. The forks are not neccesarily better, just workable. This is also the only econimical way to get a front disc. Simply remove the entire set-up from your XR200, and install the XR250 set up. I have used 87'-93' front ends for this swap, but do not believe there will be any difference on the 85'. I typically run the forks about 20-25mm above the upper clamp. You then can tailor the suspension with springs and "Emulators" for some decent trail performance. I know the purist out there will say your altering your front end geometry unless you have custom clamps fabbed up. But this machine desperately needs a better front fork and the disc. I have done several of these and have never encountered a negative feedback with the handling of the bike. It actually is surprising how good these "wifes" bikes can be ridden. I will check part #'s on the 85' in a bit, and post if I see a problem.
Fiche does show a different part# for the 85' stem assy., but it uses the same bearing and races as the ones I have used. So I would say, "Yes" it will bolt up.
I reccomend new bearings and races for a XR250, unless you can get the original races, and they are in good shape.
