Switching

  Picture of motorcycle at about 35 mph (50 feet per second)

  At the frame of the movie I am running full speed

 

  Throttle is closing

 

  Throttle is full stopped and the transmission shifts

 

  Throttle is openning

 

  And we are back to full speed.

  Full speed on/off/on happens in just 15 feet -- less than 0.3 seconds.
