The busa has a smoother running engine and smoother gearbox. The Hayabusa has more thought put into the design.[/QUOTE]
??? dont know bout the gearbox, dont get me wrong the Gen II busa is a huge improvement, but the gearbox on the 14 is almost perfect to include the great clutch, to include the whole package...and to me and other 14/busa owners, weve all agreed, both are fast equally fast, its just how you get there, the 14 is more linear in pick up and builds picking up monster torque as it goes....the busa is raw from the get go....I compare it to a brand new vette and a blown yenko ..... there both fast...the vette is reserved untill you get on it, the yenko just bucks and burns through the tires from the get go....good observation though....each once has little thing that are great..but as far as appearance and build the gen II made a huge improvement and its trim is great, the 14 is just a little to bare and not refined in the appearance side.
