The RS750 was based on the European 750 Honda motor which had chain drive where the U.S. Shadow 750 had shaft drive. I think the RS may have had a radiator on the right side, but maybe not. I can't remember. It was modified and had similar power delivery as an XR750. Unfortunately it had enough power to beat the Harley, so the AMA made it carry more weight to the point of being uncompetitive so Honda figured it wasn't worth racing if you can't win - they quit.
Several years later Ricky Graham kicked everyone's ass on a privateer RS750, winning 13 races that season.
