Kawasaki's announcement of its newest Zed is about as forthcoming on details and specifics as a general discussing troop movements on CNN. But here's some things we know for certain: The powerplant comes from Kawasaki's ZX-10R, and-just like every large-displacement naked bike with a donor engine from a supersport relative-has been retuned for additional low-end and midrange. Interestingly, Kawasaki also says the new Z's engine is more powerful than the previous Z1000's, as well as being more torquey. Which ZX-10R engine, you ask-the current or previous-generation? Best guess says it's the previous generation, as photos show the Z1000's starter on the port side; the current ZX-10R's starter lives on the right.
