The ZZR600 is powered by a 599cc, 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 36mm 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.
