For about one decade, the Ninja model from Japan held the trophy of being the fastest bike that went in production. The series is still being produced today and there is no sign of Kawasaki discontinuing it. The currently available model uses a 11.352 cc liquid cooled engine capable of reaching 186 MPH or 299 KMPH. Likewise, it can accelerate from 0 to 60 mph in just 2.5 seconds. These numbers made it the fastest consumer available bike for quite some time and still remains one of the most known models of the manufacturer.
