Shifting from first to second is done solely through the centrifugal clutch. The only thing the Optidrive does is make sure the tranny gears are not moving before it will allow you to switch into reverse. This is done via an optical sensor that reads through a crenellated gear inside the tranny. The Optidrive unit is also said to have some type of failsafe in it, but not sure about that...
