At the heart of the 2013 Kawasaki Ninja ZX -6R sport motorcycle, Kawasaki utilizes a 636 cc (38.8 cu in) liquid-cooled in-line four, four-stroke layout. Internal engine geometry specifies a bore and stroke of 67.0 x 45.1 mm (2.6 x 1.8 inches) with a 12.9:1 compression ratio.
On the scales, the Ninja ZX -6R measures 192.1 kg (424 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 831 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,394 mm (54.9 in) wheelbase engineered for quick, flickable steering geometry. The 17.03-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
