Car headlights are designed to "dip" depending on which light it is and what country they're for. So US lights dip to the right and the driver's side light will dip more than the passenger-side light.
Bike lights should throw the beam straight out with no dip.
That was one complaint about the original 750, they said it had an "automotive" style light that threw a flat beam, so when you're heeled over in a turn, the beam is lighting up the treetops above you and the road below you without lighting around the bend. They said it should have more of a circular beam.
Sinc the 750 uses a 7" headlight, refitting a more powerful custom 7" light should be easy.
