Overview 1992 1993 Designed by Tadao Baba, the first Fireblade broke new ground in terms of power and weight, decimating the 750cc sportsbike opposition with its agile handling and over-capacity motor. c In 1989, Honda tested both a 749cc and 893cc Blade prototype. c Baba insisted on using conventional and not inverted forks as they were lighter, so he designed a set ofconventional forks that looked like upside-down ones. c Honda claimed the controversial 16in front wheel (130/70 ZR16) was a weight-saving feature. c The drilled fairing and cowl were claimed to aid aerodynamics and further reduce weight. c The Fire Blade name came about after a mistranslation of its intended name of Lightning. :
