The ZX-12, by design, is not going to be as aerodynamic as the 'busa. Kawasaki's design thoughts carry a much different overall theme.
The original black and white photos, which were initially run as "spy" photos on DRAGBIKE.COM, and later found everywhere else on the web, and in magazines, are photos of the "mule", which is the first hand built bike. The actual production models will look similar, and the digitally enhanced '9 in Cycle World is actually pretty darn near what it will be.
Keep in mind, the quickest bike in the Cycle World/UFO shootout, was the Mr. Turbo ZX-11, and was as aerodynamic as a barn door.
No doubt.. the 12 will be a contender in overall top end speed, and will probably go to bat very well in the elapsed time department, and in fact, prior to my doing an article with the 'busa, I planned on building one for the shootout.
Since, I am now an owner of the Suzuki.
