The 2012 model also has a slipper clutch very similar to that one found on the current ZX-10R.
GREAT PAIR OF CANS: Kawasaki has taken a great deal of trouble over not only getting air into the larger-capacity engine, but also extracting it. That's two seriously mega-mufflers.
There’s also a programmable launch light and shift light and an “Eco” indicator that tells you when you’re getting optimal economy (a moot point on a bike that is unlikely to be bought for fuel economy considerations).
NOW - AND THEN: The 2012 Kawasaki ZX-14R (left) and the preceding model - there are some big differences.
