A Honda Cub does not need a hand lever to press to change gears but the user can still change gears manually by pressing on a foot clutch. Why cant they just replace all manual transmission motorcycles (with hand lever clutch and foot pedal clutch) to semi automatic (no hand lever, but with foot pedal clutch)?

It’s a centrifugal clutch. As engine rpms increase, centrifugal force cause the clutch plates to expand outward and engage the drive train. There’s also a lever attached to the shifter arm to slightly disengage the clutch as you start to change gears.
