The relatively new (2015) Kawasaki H2 is a mass produced supercharged light weight 1 litre road bike putting out about 200hp. There's not much on two wheels that can keep up with it.
To ensure the design was bulletproof Kawasaki initially developed a prototype running much more boost producing over 300hp at the rear wheel, and then decided to produce and sell it as well. It can't be road registered though because they removed the front headlight and mirrors (replaced by winglets), as well as a couple of other minor details. At first glance though they look the same.
Some guy over in Turkey decided to see if he could break the 400kph barrier on a nice new bridge over there, with no traffic of course! The bike had no mods except a slight change in gearing and a slick tire. The result for the H2R was 400kph in 26 seconds. Beat that!
This is some "testing" of the road legal H2 on some public highways by a couple of hoons lol. The other bike is a Kawasaki ZX10, plenty fast enough already! Warning, they get a bit excited so there are a couple of expletives uttered here and there.
