You won't find much that will do a direct swap, but with some work you can probably get something to work.

With that size your looking more at the earlier model CBR600's for the rear.

Of course this all depends on the year RS you have. Early model RS's had the left hand drive chain, while the later models had the right hand. Pretty much all honda road bikes have a left hand drive chain.

Front won't be as bad. Just may need to make some custom spacers, and figure out the whole brake disc thing.
