Call it an alternate route to the evolutionary trajectory toward smaller, lighter, faster Ninjas like the 2011 ZX-10R. Bikes that get closer to the track and farther from everyday reality year after year. Just don't call it a dressed-up Z1000, which wears too much plastic to be naked anyhow. Kawasaki rolled out the underdressed version first because the home office figures to sell more copies everywhere except here, but both 1043cc fours were fleshed out together. Once you peel back their dissimilar plastic skins, both bikes are pretty much the same. Same relatively long-stroke four tuned to lay down most of its muscle in the middle of the rev band. Same gear-driven balance shaft squelching second-order vibration. Same stiff, five-piece, stressed-member, die-cast aluminum skeleton. Same 41mm fork and horizontally mounted shock. As a wise far-western philosopher once said, if it ain't broke, don't fix it. Lighter, six-spoke cast wheels are new to the Ninja 1000 parts manifest, along with a list of functional touches that make life on the street a little more interesting and a lot more comfortable.
