Built around Kawasaki's sport motorcycle platform, the 2025 Kawasaki Ninja Zx4Rr Krt Edition ABS features a 400 cc engine configuration. Internal engine geometry specifies a bore and stroke of 57.0 x 39.1mm with a 12.3:1 compression ratio.
On the scales, the Ninja Zx4Rr Krt Edition ABS measures 414.5 kg (914 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 31 mm (1.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 54 mm (2.1 in) wheelbase engineered for quick, flickable steering geometry. The 4-liter (1.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
