When unveiled in late 2014, the Kawasaki Ninja H2R became not only the most powerful production motorbike, but also promised to be the fastest in a straight line and now, it’s become just that, albeit with the help of some tuning.

While being ridden by Ryuuji Tsuruta at a private test track, this H2R managed to reach an insane 385 km/h (239.3 mph), putting it comfortably ahead of the MV Agusta F4 R 312’s previous 310 km/h (193.24 mph) top speed record.

However, as the H2R isn’t road-legal and is restricted to the racetrack, it can’t be considered the world’s fastest. Additionally, the supercharged engine of this example has been tweaked from 310 hp to the 400 hp mark, aiding in its performance.

Not satisfied with 385 km/h, Trick Star, the Japanese workshop behind this H2R, believes that it can reach 400 km/h (248.6 mph) if a circuit with a longer straight can be found.
