Positioned in Kawasaki's sport motorcycle lineup, the 2024 Kawasaki Ninja ZX-4R ABS utilizes a 399 cc (24.4 cu in) liquid-cooled in-line four, four-stroke layout. Internal engine geometry specifies a bore and stroke of 57.0 x 39.1 mm (2.2 x 1.5 inches) with a 12.3:1 compression ratio.
On the scales, the Ninja ZX-4R ABS measures 188 kg (414 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,379 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 15.14-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
