This has always been a brilliant streetbike engine – torquey, smooth, and blessed with impressive top end performance, yet enough satisfying low- and mid-range oomph to please novices and experts alike. Figure in the Ninja 650 engine’s estimated 50-mpg* fuel economy, precise fuel injection and its pleasing twin-cylinder throb, and you’re looking at what just might be the most flexible and satisfying streetbike engine on the planet.
Wrapping around that wonderfully usable engine is an all-new twin-pipe perimeter frame that offers increased rigidity vs. the old Ninja’s trellis layout, yet retains the narrow-waisted design that results in a comfortable reach to the ground.
Folks watching you ride by will see a sleeker and more aggressively styled motorcycle, as well. Pull away from a light and the 650’s torquey engine, light-pull clutch and perfect throttle response make quick work of the job. Experts will love the new Ninja’s powerful yet flexible engine, modern suspension, disc brakes and nimble handling.
