Sensitive electronic con-
trol
It takes skill and sensitive con-
trol of the brakes to pull up
safely on a motorcycle. If the
front wheel brake locks and the
wheel skids, the necessary lon-
gitudinal and lateral stabilising
forces are lost, and a fall can
result.
For this reason, the rider sel-
dom makes full use of available
braking performance in an
emergency.
Anti-lock braking at both
wheels greatly reduces the risk
of accidents even when road
conditions are poor, and short-
ens braking distance by making
more efficient use of the motor-
cycle’s braking capability.
ABS helps optimise safety in
emergency-braking situations
when the motorcycle is travel-
ling in a straight line.
Extra safety reservesBut remember: the potentially
shorter braking distances
which ABS permits must not be
used as an excuse for careless
riding. ABS is primarily a means
of ensuring a safety margin in
genuine emergencies.
– Never ride without due care and attention, or assume that
good fortune will protect you
from your own foolhardiness
– Keep within the permitted speed limits
– Take care when cornering. When you apply the brakes on
a corner, the motorcycle's
weight and momentum take
over and even ABS is unable
to counteract their effects

The ABS is taking effect:– if a pulsating sensation is per-ceptible through the hand-
brake lever or brake pedal
when you apply the brakes
L Note:
Pulsation at the brake lever indi-
cates that the ABS is in action.
The ABS prevents the rear
wheel lifting, depending on rid-
ing style and the applicable
boundary conditions.
e Attention:
If the brake lever can be moved
right to the limit of its travel, this
indicates a mechanical or hy-
draulic fault.
It is advisable to consult an
authorised BMW motorcycle
dealer, and have the problem
rectified.

ABS is out of action:
d Warning:
If there is a fault in the ABS
system – as indicated by
warning light 1 –
the reserves of safety nor-
mally afforded by ABS are not
available until the defect has
been put right.
There is a risk of dropping the
motorcycle if the brakes are
applied too hard and the
wheels lock or the rear wheel
lifts clear of the ground as a
result of a high level of front
tyre adhesion.
OEOptional extra
d Warning:
The ABS shuts down after ap-
prox. 10 seconds if you ride
with only one wheel in con-
tact with the ground.
– at speeds below 6 km/h (3 mph) (or 12 km/h (6 mph) if
brake lever was actuated
beforehand)
– when the ignition is switched
off
– if the battery is defective or
flat (indicated by ABS warning
light)
– if there is a fault in the ABS
system (
b65)
The brakes remain fully
operational, though without
the reserves of safety
afforded by ABS.

d Warning:
When the ABS is deactivated
– as indicated by ABS warning
light 1 flashing – none of the
safety reserves normally
offered by the anti-lock brak-
ing system are available until
the ABS function is reacti-
vated.
There is a risk of dropping the
motorcycle if the brakes are
applied too hard and the
wheels lock or the rear wheel
lifts clear of the ground as a
result of a high level of front
tyre adhesion.
After you press the starter
button, check whether the
ABS is still deactivated.  With the motorcycle at a
standstill and the engine run-
ning, press ABS button 2 and
hold it down for 3 seconds
– Warning light 1 starts flashing
 Release ABS button 2
– The ABS function is deacti- vated
– Warning light 1 continues
flashing, but at a slower rate,
to remind you that ABS has
been deactivatedOEOptional extra

Arrive safely
Training means extra safety
Cornering and braking
need to be practised
Develop a "sixth sense" for
potentially dangerous situa-
tions. What this means: look
ahead, plan how to avoid possi-
bly dangerous situations and
study other road users’ behav-
iour with a degree of healthy
scepticism.
– Take bends smoothly and rhythmically, avoiding harsh
braking and acceleration
– Approach bends slower than
you feel they can be taken; a
neat riding style will get you to
your destination more safely
than sheer speed
– Ride at the inner edge of the
ideal line, look ahead and plan
to leave the bend as smoothly
as you entered it Allow for reaction time when
judging braking distances.
– At 50 km/h (approx. 30 mph),
for instance, every second
lost represents a further dis-
tance of about 14 metres
(46 feet) before the brakes are
applied
– At 90 km/h (approx. 55 mph),
this distance grows to
25 metres (82 feet).
Practice applying the brakes
with and without an extra load
on the motorcycle, and study its
reactions on various kinds of
road surface.
Work up to the wheel lock limit
gradually.
BMW has a worthwhile safety
contribution to make in this area
too – BMW Safety Training.
These programs are a wonder-
ful opportunity:
systematic basic and follow-up
training enables you to master
situations close to the limit and
keep your motorcycle under
supreme control whatever hap-
pens.
