When work began on a new sport motorcycle in the late 1980s, Tadao Baba focused on how the machine would feel through a bend. Years as a development rider had shaped his belief that a motorcycle should respond predictably to its rider. The emerging CBR900RR Fireblade therefore began with control as its guiding idea, at a time when peak power and top speed often dominated the conversation about sports bikes.
Baba chose a capacity of around 900 cc, seeking the light chassis feel of a 600 cc machine with performance closer to that of a larger motorcycle. He set targets of 185 kg dry weight and no more than 200 kg with fluids. The team looked for savings throughout the machine rather than expecting one component to shed all the required weight. The new model was shown in Milan in November 1991 and reached the market in 1992.
The first generation combined a compact four-cylinder engine, an aluminium frame and a 16-inch front wheel. That wheel size helped accommodate a wide tyre while retaining the desired overall diameter. Later Fireblade generations changed considerably and gained power, but the original design question remained useful: how confidently can a rider put the available performance to work? Baba’s project showed that weight and handling deserve as much attention as the numbers in an engine specification.
