Kawasaki has been carefully crafting its popular Ninja lineup for decades, and the 2019 ZX-6R has received a number of upgrades to help it stand out from the competition on the motorcycle dealer’s showroom floor. This middleweight sportbike punches above its weight courtesy of a long-stroke 636cc inline-four, which offers more midrange torque than a typical 599cc supersport yet still spins to 16,000 rpm. An electronic quickshifter and a one-tooth-smaller countershaft sprocket were added for ’19 to help improve acceleration. The latest ZX-6R also wears new bodywork that is more clearly matched to its Ninja heritage, including the best-selling twin-cylinder Ninja 400. LED lighting, comfortable ergonomics, and forgiving suspension settings make for a motorcycle that is well-suited to life on the street.
