The official name on Honda RC45 is Honda RVF750R, but it is mostly called RC45. It was produced in a number of only 200 pieces in order to fullfill the homologation requirements to be allowed to compete in the World Championship for Superbikes. That makes it one of the rarest Honda bikes ever produced.
Honda RC30 was introduced in Japan 1987, in Europe 1988 and in the USA 1990. Fred Merkel won the World Championship both 1988 and 1989 on it. Both these years, plus 1990, Honda also won the constructor championship with RC30.

- A bit sharper front fork angle.
