I have a BW200N and the sprocket on it isnt dished at all, was this a later thought on newer models, or is mine not stock. The rear chain seems to run fine etc.
The sprocket is dished on a 350, but I believe that it is flat on a 200 and will not interchange between the two bikes. If you want to gear down for a bit slower top speed, you will need to increase the size of your rear sprocket, or downsize your front sprocket on your secondary (rear) chain. I am not sure what is available for the 200's, but our beloved 350's sprockets are becoming increasingly difficult to find. Good luck!
