Adjusting beam throw
\f Note:
When the basic setting is cor-
rect, headlight beam throw is
regulated when spring preload
is adjusted to suit load.
Have the headlight basic set-
ting adjusted by a specialist
workshop, preferably an
authorised BMW motorcycle
dealer.
\f Note:
Adjust beam height so that
oncoming traffic is not dazzled.
Make sure that the throw of the
light cone adequately illumi-
nates the road ahead of you.
Adjusting to suit load: Change the spring strut set-
ting to suit the load (
b 42)
– Spring preload has an effect
on headlight throw
Do not pivot the headlight down
to adjust beam throw unless the
motorcycle is heavily loaded.
