Front will take pretty much any of the Honda spoked wheels, for 19" use CB450/500T, 500/550F, CB750 sohc. You can even use front from CB77 if you wanted a 18" with drum brake. CB350/360 can also be fitted. If you have the 'right' forks you can bolt on dual discs. As far as I know, the rear has to be dismantled and have spoke flanges bolted on. I would probably use 1/4" 6061 plate to make the 'rings'
