Technical data

Checking brake-fluid
level, rear brakes
A low fluid level in the
brake reservoir can allow air
to penetrate the brake system.
This significantly reduces braking
efficiency.
Check the brake-fluid level at
regular intervals.
Make sure the ground is level
and firm and hold the motor-
cycle upright.
Check the brake fluid level in
reservoir 1.
Wear of the brake pads
causes the brake fluid level
in the reservoir to sink.

If the brake fluid level drops be-
low the permitted level:
Have the defect rectified as
quickly as possible by a spe-
cialist workshop, preferably
an authorised BMW Motorrad
dealer.
