Austrian firm KTM
came out with their X-Bow last year, showing that it is possible for a motorcycle company to create a powerful sportscar. The KTM X-Bow R model was powered by an Audi
-sourced 2.0-liter TFSI engine that could put out 300hp. Kawasaki's ZX-770R concept will leave that number in the dust, sporting a twin-turbocharged V6 engine that can pump out 770hp. The ZX-770R was developed by Dutch designer Sabino Leerentveld.
