2011 Kawasaki Ninja 1000 Looking for an Open-class sportbike without the racetrack riding position? That's exactly what this new Ninja is all about. Take the torquey, liquid-cooled inline-Four from the Z1000 naked, wrap it in attractive bodywork, give it an upright seating position and this is the result. The short-stroke engine offers awesome real-world performance smoothed out by a crankshaft-driven balance shaft. The aluminum frame sweeps over the engine, affording the bike a narrow width between the rider's legs. A fully adjustable 41mm fork and a shock adjustable for preload and rebound damping provide excellent ride quality.
