Positioned in Kawasaki's sport motorcycle lineup, the 2006 Kawasaki Ninja ZX-12R relies on a 1198 cc (73.1 cu in) liquid-cooled in-line four, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 83.0 x 55.4 mm (3.3 x 2.2 inches) with a 12.2:1 compression ratio.
On the scales, the Ninja ZX-12R measures 210 kg (463 lbs) dry. Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,450 mm (57.1 in) wheelbase engineered for balanced agility and highway composure.
