How fast is 400 km/h? Fast enough that getting to it in a mere 26 seconds is a world record feat. The most successful World Supersport rider of all time Kenan Sofugoglu got Turkish officials to shut down the entirety of the bridge which strectches across the Gulf of Izmit. His Kawasaki Ninja H2R sped up to 400 km/h (~250 miles per hour) in under thirty seconds to minimize the possibility of tire blowout, and boy did he nail it. You’ll have to watch it twice through just to appreciate how fast it is.
