Look closely. Move beyond the obvious similarities in engine size and mission statements. After a few days and miles, each combatant will assert its own distinct character. As the once and future king of seamless, digital refinement, Honda's latest F3 feels small, tight, narrow, agile and ergonomically correct. At 459 pounds soaking wet, it is seven pounds heavier than Kawasaki's more compact ZX-6R. The Ninja's rider and passenger accommodations are less capacious than the Honda's as well, making the Kawasaki a more comfortable ride for the sub-six-foot set. Adjustable brake and clutch levers are exclusive to the Ninja, as is the idiot-resistant neutral finder.
