At the heart of the 2011 Kawasaki Ninja ZX-6R sport motorcycle, Kawasaki pairs a 599 cc (36.6 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 67.0 x 42.5 mm (2.6 x 1.7 inches) with a 13.3:1 compression ratio.
On the scales, the Ninja ZX-6R measures 191.1 kg (421 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 815 mm (32.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,400 mm (55.1 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.
