2011 Kawasaki ZX-10R teaser – Click above to enlarge

In case you hadn't noticed, there's a new crop of superbikes terrorizing the roadways and racetracks of the United States. And more than any other point in recent history, the Big Four Japanese brands aren't leading the way. Instead, it's the European brands – Specifically Aprilia, BMW, KTM and MV Agusta – that are encroaching on Honda, Kawasaki, Suzuki and Yamaha's territory.

Team Green isn't likely to let the newest challengers turn its flagship Ninja into an also-ran, and the latest evidence of such can be seen in a new teaser of the 2011 Kawasaki ZX-10R. Expect a completely new motorcycle for next year, including a new engine, frame and suspension package. In order to compete with the latest from Europe, we'd also imagine the literbike to get an upgraded electronics package.

While we don't have any details on those hard bits, we do have one rendering that shows an aggressive new look with a gaping ram air scoop front and center. Want more? Check out an enlarged version of the teaser image above and be sure to click past the break for the accompanying video.
