no, i believe the bolt patterns are different. you'll need to use the rotors that go with that wheel.
the easiest way, though, is just to put the entire front end (wheels, brakes, forks, triple clamps) off an 89-91 750 on your bike. the steering stem goes right into the frame.
If you have access to a suitable lathe you can machine the inside dia to fit the 17 wheel and then redrill the bolt pattern between the existing set of holes so the rotor will now bolt on 17 or 18
