Before loading the Ninja onto the Cycle World dyno, we placed it on our automotive scales and recorded a wet weight of 432 pounds. On our in-house Dynojet 250i dynamometer, the 2023 Kawasaki ZX-6R produced 108.4 hp at 13,200 rpm and 45.8 lb.-ft. of torque at 10,900 rpm. For reference, the 2023 Suzuki GSX-R600 produced 102.9 hp at 13,520 rpm and 44.0 lb.-ft. of torque at 11,580 rpm. The ZX-6R’s extremely linear power delivery and flat torque curve is routine for this class. Although the increased low-end torque is noticeable, like any 600cc sportbike, revving it to the moon yields the best results.
