There doesn't seem to be shaft drive e motorcycles currently however Zero and the Livewire del Mar have the drive sprocket at the swingarm pivot where others have the drive sprocket more forward or maybe even more to the rear or hub drive.  This must contribute to chasis jacking.  Hold the front brake and apply some power at a stop and see what happens.  That is about all I can contribute to this discussion.  Usually at least with dirt bikes the two sprocket centers and the swingarm pivot are in line at about 1/3 compressed.   Most likely the properties this has are expected from the rider.  This is when the chain is tightest.  Why my KTM is tightest at fully extended is a mystrey to me.  BMW and later when the owned Husqvarna motorcycles had a 450cc swingarm centered sprocket race bike and a number of top riders they hired got hurt on it.
