Let the rumors fly as to what Kawasaki has up its sleeve, because Team Green has registered “Ninja R2” with the US Patent and Trademark office, as well as similar offices internationally.

The trademark application is fairly broad in what the name can be used for, but knowing Kawasaki’s product line, a new motorcycle can be expected from the “Ninja” name.

What that motorcycle could be, is up for debate. Some draw a line between the “Ninja R2” name and the recently revived “Ninja H2” model, and thus see another supercharged machine to come from Kawasaki. Others hear the whispers of a small-displacement sport bike, perhaps one with a stratospheric rev-limit (our pick).
