A mid-size supersport ZX-6R built around the 636 cc engine, tuned for low and mid-range power that makes it easier in traffic and on winding roads. Electronic aids are three-mode traction control, selectable power modes, optional KIBS ABS and a quickshifter for clutchless upshifts. It has Showa suspension and Nissin brakes, and a seat set up for a slimmer riding position.
