To be fair, this is Kawasaki we're talking about. Only company I know that's nuts enough to put out a 250cc inline 4 screamer in the ZX25R. Then also produce the H2 which has a supercharger with holes cut into it so that you can hear the chirping of the impeller blade tips exceeding the speed of sound and generating a small sonic boom.

Don't know of another large motorcycle company that's willing to try wonderfully silly things like this.
