Between the Honda CBR Hurricane and the Honda CBR Gullarm there are many differences. Hurricane was the earlier model to Gullarm, which has a single large front disk, 3 spoke wheels a fuel pump etc.. The Gullarm was a completely new redesigned bike with a gull shaped swing arm that was adopted from the NSR250, two disks at front, 6 spoke wheels, a completely new set of VP carburetors, vacuum operated pump, etc...
Between the CBR Gullarm and the Fireblade, which was the last model in the series has minor differences except CBR Fireblade has a reduced power output of 40 ps (30 kW), which was due to a change in Japanese law. Apart from that Fireblade is on-light, less wholes in the front disks compared with Gullarm front disks.
Those are the differences according to my knowledge. Hope this helps.
Cheers!
