Power Modes allow available power and throttle response to be selected to suit conditions. On the supersport Ninja ZX-10R, three modes are available: Full, Low (which limits power to about 60% of Full) and Middle mode, which falls between the two. More than a simply bisecting the Full and Low mode power curves, in Middle mode performance characteristics vary depending on engine speed and throttle position. At less than 50% throttle application, engine performance is essentially the same as in Low mode. However, opening the throttle past 50% allows performance up to that of Full power to be accessed. This advanced engine management system allows mild engine character for normal riding situations, with the option to tap into greater power for a quick burst of acceleration. Variable Middle Mode offers riders the ability to alter engine performance and delivery by conscious use of throttle control (either for ease of control when riding in the city, or for greater response when the rider calls for quick acceleration). This kind of technology allows supersport machines to be enjoyed in a broader range of situations.
