ditto what GSP said.
HUGE cult following with LOTS of modifications and parts readily available.
if it's a lambourghini orange 1988 (if i recall correctly...) with a CBR600 F2 front end that you're thinking of purchasing... she used to be mine!
the CBR front end mod was to fit more current/standard (read wider) sportbike tires and stronger brakes from the stock single disc. other popular mods were TBR (Two Brothers Racing) exhaust systems and adapting a VFR 750 (circa 1995-98) rear wheel (again for a wider rear tire).
the Hawk was an excellent all-rounder street-fighter type motorcycle that was well ahead of it's time. it wasn't really a best seller for Honda so they dropped it from their lineup - which ironically - turned it into an instant "collector's item".... hahaha - you gotta love marketing.
everything you ever wanted to know about the Hawk (but were afraid to ask? - haha) can be found at this website... right down to a downloadable .pdf file of original Honda Manuals. lots of pics from Hawk enthusiasts world wide... have a couple of hours ready before you start browsing! another Hawk owner/enthusiast is Miles - the service manager at RMS.
hope this helps... and GO FOR IT! that was a great bike...
