Engine
Kawasaki engineers utilized a "stack" design for a liquid-cooled, 998 cc inline four-cylinder engine. The crank axis, input shaft and output shaft of the "Ninja" ZX-10R engine are positioned in a triangular layout to reduce engine length, while the high-speed generator is placed behind the cylinder bank to reduce engine width. With a bore and stroke of 76 mm × 55 mm (3.0 in × 2.2 in), the ZX-10R engine's one-piece cylinder and crankcase assembly reduces weight and increases rigidity. The DOHC are machined from chromoly steel built for strength, four valves per cylinder improve high-rpm breathing, and the forged, lightweight pistons offer high heat resistance to further enhance the bike's power-to-weight ratio.

Famous quotes containing the word engine:
“There is a small steam engine in his brain which not only sets the cerebral mass in motion, but keeps the owner in hot water.”
—Unknown. New York Weekly Mirror (July 5, 1845)
“The will is never free—it is always attached to an object, a purpose. It is simply the engine in the car—it can’t steer.”
—Joyce Cary (1888–1957)
“Industrial man—a sentient reciprocating engine having a fluctuating output, coupled to an iron wheel revolving with uniform velocity. And then we wonder why this should be the golden age of revolution and mental derangement.”
—Aldous Huxley (1894–1963)
