Once you start to change gears, there begins a very intense discussion between the shift actuator, the clutch actuator and the ECU. The shifters--foot pedal or hand switch--report to the ECU, which tells the clutch actuator to disengage the clutch. That actuator reports "Job Done" back to the ECU, which then tells the shift actuator to actually change gears; completion of that act routes another message to the ECU, which goes back to the clutch actuator, telling it to re-engage the clutch at an appropriate speed. Yamaha says the entire shift event takes about 200 milliseconds, and that a typical manual shift takes 300 milliseconds. The average time of a human eye blink is 300 to 400 milliseconds.
