The 2025 Kawasaki Ninja 500 base model is powered by a liquid-cooled, 451cc parallel-twin engine that generates 51 horsepower at 10,000 rpm and 31.7 lb-ft of torque at 7,500 rpm. This performance is managed through a six-speed transmission equipped with a standard assist and slipper clutch. The motorcycle is built around a lightweight, high-tensile steel trellis frame supported by a 41mm telescopic front fork and a preload-adjustable horizontal back-link rear suspension. Braking power comes from a single 310mm front disc with a two-piston caliper and a 220mm rear disc. The bike features a rider-friendly 30.9-inch seat height, a 3.7-gallon fuel capacity, includes ABS.
