There’s been a lot of buzz about Kawasaki’s relentlessly teased H2 sportbike, but information with any details is thus far practically non-existent. The only things certain are that it will be powered by a supercharged inline-Four engine and packaged in a fully faired sportbike platform.

Will the H2’s engine’s lineage include the ZX-10R?

Or the Z1000, as we originally anticipated?

But a little digging on the interwebs turned up NinjaH2.org in which we found this thread: http://www.ninjah2.org/forum/engine/1289-kawasaki-ninja-h2-insider-confirmation-engine.html

The source claims some sort of insider info, a friend of a friend thing, and he purports the supercharged engine will meet or exceed 225 crankshaft horsepower. Interestingly, the source says the H2’s inline-Four powerplant might be a bespoke design, neither the Z1000/Ninja 1000 roots we guessed  nor the ZX-10R’s.

Perhaps the H2’s engine will be the unholy spawn of the Z1000 (left) and the ZX-10R (right) that rises up to bludgeon them both in their sleep.

We’re not 100% sure if the engine will be an all-new design or a variant of one of Kawasaki’s two current liter-class mills, but, based on MO’s own conversations with Kawasaki insiders, we can believe the post’s closing line: “This thing will be absolutely the quickest and most powerful Kawasaki motorcycle of all time, by far.”
