Positioned in Kawasaki's sport motorcycle lineup, the 2015 Kawasaki Ninja RR utilizes a 149 cc (9.1 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 28.2 HP (20.6 kW) at 11,000 rpm while maximum torque reaches 20 Nm (14.8 lb-ft) at 9,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 189.3 HP per liter and a 2,000 rpm working window between peak torque (9,000 rpm) and peak power (11,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Ninja RR measures 134 kg (295 lbs) dry, translating to a power-to-weight ratio of 0.21 HP/kg (4.75 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,305 mm (51.4 in) wheelbase engineered for quick, flickable steering geometry. The 10.8-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
