Works lightly on low torque, and increases the plate pressure as the torque increases. The slipper clutches lift the plates for you when there is a high torque in the reverse direction.
Got to be possible.
You might find if you slipped the clutch to set off too fast it would prevent you slipping it . No idea really.
The point is that many riders do have a problem with heavy clutches, as evidenced by the number of queries on how to make it lighter.
But as I've said, I've no idea how it could be done practically.
