Kawasaki built the -14 for one purpose.........to succeed where the -12 failed.
See it's in that point that you Busa guys have the design goals of the ZX12R confused.
Apparently, none of you have read the SILVERBOOK which was given to those who purchased the 2000 ZX12R (new). It's basically a small book about the creation of the ZX12R from design goals to R&D to concepts to the final product. Nowhere in the book did it say anything about their main goal being to beat the Busa in top speed or the 1/4 mile. In fact, the ZX-12R began development BEFORE the Hayabusa, in response to the CBR1100XX (initially). Suzuki just beat Kawasaki to the punch and upped the ante when they dropped the bomb in 1999.
Kawasaki clearly stated that they wanted to build the biggest fastest most powerful NINJA the world has ever seen. A bike that could be used as a missle on the highway while still being able to handle and feel like a NINJA sportbike. Essentially, an all around dynamo of a machine that would run toe-to-toe with the Busa and hold it's own against the current crop of open class sportbikes on the street.... all while retaining the styling of the current Ninja sportbike lineup.
The media hyped up the whole "ZX12R = Busa killer" thing in 1999 during pre-production... and when 2000 rolled out the production ZX12R's, it could only match the Busa at best in terms of top speed and 1/4 mile.... whereas it was expected to demolish it much like the Busa did to the CBR1100XX just a year earlier.
The ZX12R was in no way a "failure". It wasn't designed with one purpose in mind like the Hayabusa, and it still achieved similar performance....all while not having to cut corners, borrow from peter to pay paul, and will LESS displacement (only 62cc larger than the CBR1100XX's 1137cc's). Did the ZX12R beat the Busa in stock vs stock comparo's? Some mags say yes, some say no... doesn't matter anyway since nobody who's racing, races with a stock bike.
This all being said, the ZX14 WAS designed with the sole intention of reclaiming the Speed Crown and dethrowning the Busa without question where as the ZX12R left much up to debate (exactly 6 years of it!!).
The 14 is essentially just Kawasaki's version of a Hayabusa with ZX12R heritage. Best of both worlds... amazing torque via displacement like the Busa.... and screaming peak power like the ZX12R, only difference is that it does both things better than either than Busa or ZX12R!
