This is one awesome motorcycle!
If everything is still factory stock and you have a Xenon headlight, then the high beam is still an ordinary halogen bulb. The stock Xenon headlight is bright and bluish, the other bulbs are not as bright and they are yellowish.
The throw adjuster lever is normally straight out. You flip it to the right only if your primary Xenon bulb burns out (and you use the high beam as a normal headlight), or if you are carrying a very heavy load and need to drop the low beam down to avoid projecting glare in the rear windows of cars.
It is important to get the Xenon headlight adjustment position right. The beam is unusual. In the US (where we ride on the right side of the road), it has a sharp cutoff that stays flat from the left side, across the center (below car rear windows) and then rises at ~45 degree angle going to the right. (For UK/Australia/Japan etc. the beam does the opposite.)
The factory Xenon can be so bright that you can trigger road rage from car drivers, even if it is correctly adjusted.
Here is the basic adjustment:
1. Make sure the throw adjuster lever is in the neutral (straight out) position; not flipped to the right. Adjust the suspension to "basic". I assume that means single rider, normal.
2. With the rider on the seat, measure the height from the ground to the center of the headlight. BMW's default rider is 85 kg.
3. With the rider on the bike, put it on a level flat surface, facing a vertical wall. Mark the wall at the headlight center height you measured in step 2, above.
4. Position the bike so that the bottom of the front tire (the contact patch) is 10 meters from the wall.
5. Start the engine to turn on the headlight.
6. Use a socket wrench to turn the adjustment nut (inside the throw adjuster lever) until the light/dark boundary projected on the wall is 15 cm below the mark you made (15 cm below the height of the center of your headlight).
7. Adjust the left/right position (lateral throw) by turning the other adjustment nut with the socket wrench. There isn't much guidance here, but I would make sure that the 45 degree upward tilt starts past the right side mirror of a hypothetical car in front of you.
