2007 Kawasaki ZZR600, These middle weight sport bikes deliver the perfect package, they just do everything right - The quick practical and affordable sportbike. The ZZR600 sets the standard for practical middleweight performance while offering class-leading comfort and cutting edge style. Well on its way to legend status, this modern sportbike has earned a healthy respect from the motorcycling public and finicky motojournalists alike, thanks to its excellent overall balance and scintillating performance. The ZZR600 is powered by a 599 cc, liquid-cooled, inline, four-cylinder engine with dual overhead cams and four valves per cylinder. Kawasaki’s Twin Ram Air Induction system, which features a leading-edge air scoop at the front of the bike’s fairing, forces cool air into the ZZR600’s airbox and then onto its four 36 mm carburetors. The carburetors also feature the Kawasaki Throttle Responsive Ignition Control (K-TRIC), which monitors the throttle position and adjusts ignition timing for the engine’s four spark-plug mounted ignition coils, maximizing the ZZR’s performance at every rpm. The high-tech engine is matched to a close-ratio six-speed transmission, providing the ZZR600 rider with the best gear for any riding situation, whether it’s freeway droning or handling some back road twisties.
