I remember back in the 80's I fitted cast wheels on my four four from a Yamaha xs250 which had a drum at the back and the sprocket from an RD250 fitted and was the right number of teeth, I cant remember if the front wheel was of an RD250 or XS I had to get a few mm machined of of the disk diameter and it worked with the Honda spindle and brake, I think in those days it was for practicality rather than style.
