Closest thing possible is a 200M fork, with mounts welded onto if for the rack and headlight bracket/guard.
There were bolt-on racks available for the 200M fork, but finding one, and for a decent price is going to be very difficult.
Unless you can purchase an entire 200M, strip the front end then sell the rest, it's still going to be expensive. All
parts prices have gone through the roof. It may be just as easy to find a complete 250ES front end for the same or less cost. Those will fit too, but may take some finagling with the stem bearings, IDK.
It's a little late now, but anyone looking at purchasing a 200E/ES needs to really check the forks. 9/10, they're junk and seized. It's the biggest problem with that model and there's no easy or inexpensive way to repair or replace them.
