OVERVIEW AND OPERATION

14
Before each ride, carry out a safety
check using the checklist.
Take the safety check seriously. Carry out
maintenance activities before you start your
ride or ask a specialized Sachs dealer to do
so. This will provide you with the certainty
that your motorcycle corresponds to traffi c
regulations. A technically faultless motor-
cycle is a basic requirement for the safety
of both yourself and other road users.
Before starting your ride, check the fol-
lowing:
– Steering (smooth and free of play)
– Clutch lever play
– Lubricating oil quantity
– Fuel quantity
– Front brake
– Rear brake
– Tyres (profile and pressure)
– Telescopic fork
– Load / lights
– Total weight
– Lights
– Brake fluid (level)
– Brakes (operation)
In case of problems or difficulties, contact a
Sachs dealer, who will do everything pos-
sible to assist you.
SAFETY TEST
Checklist
WARNING
While the engine is running or the ig-
nition is on, do not touch the ignition
system.
FIRE HAZARD
The exhaust system becomes very hot.
While riding, idling or parking, make sure
that no inflammable materials (e.g. hay,
leaves, grass, coverings or luggage, etc.)
can come into contact with it!

SAFETY TEST
Load / lights
WARNING
For the sake of your safety, use only
original Sachs accessories or products
released by Sachs.
Sachs cannot judge for each third-part
product whether it can be safely used in
combination with your Sachs motorcycle.
Nor can a official approval give such a guar-
antee in all cases, since the test scope is
not always sufficient.
NOTE
Sachs accessories and Sachs-approved
products as well as qualified advice are
available from all specialized Sachs deal-
ers.
Correctly loaded
- Make sure that the left-right weight dis-
tribution is balanced.
- Check that fastenings are correct and
tight.
- Do not transport bulky loads.
- Do not cover the lights.
WARNING
The total allowable weight may not be
exceeded.
Check the tyre pressure.
Checking the lights
WARNING
Before any ride, check the operation of
all lighting components.
- Check that the headlamps and lenses are
clean.
Ride safely
CAUTION
Riding safety is largely also determined
by the manner of riding.
Therefore:
– Put on a tested/approved safety helmet
and correct close the buckle.
– Wear suitable protective clothes.
– Rest your feet on the footrests.
– Do not ride if your riding ability has been
compromised.
Your reactions can be adversely affected
not only by alcohol, but also by drugs and
medicines.
– Strictly observe all traffic regulations.
– Always adapt your riding speed to the
traffic and road conditions.
On smooth, slippery roads take into account
that your riding stability and braking power
are limited by the grip of the tyres on the
road top.

RIDING INSTRUCTIONS
Ride economically and be aware of the environment
Fuel consumption, environmental pollution
and wear of engine, brakes and tyres de-
pend on various factors.
Your personal riding style is highly deter-
minant for economical fuel consumption
and exhaust gas and noise generation.
While idling, the engine takes a long time
to warm up to operational temperature. In
the warm-up phase, however, the wear level
and pollutant emissions are very high. It is
therefore best to start riding immediately
after start-up.
Avoid rapid acceleration
Open the throttle not further than needed,
in order to reduce fuel consumption as well
as pollution and wear levels.
Do not use excessive revs; change up as
soon as possible and do not change down
until it is necessary to do so.
Ride as evenly as possible and look
ahead as far as possible.
Unnecessary acceleration and hard braking
cause high fuel consumption and increased
pollution levels.
Turn the engine off when waiting in traf-
fic.
Different riding conditions affect fuel con-
sumption. The following conditions are un-
favourable for fuel consumption:
-High traffic density, especially in big cities
with many stops for traffic lights.
-Frequent short rides with repeated starts
and warm-ups of the engine.
-Riding in a column of motor cycles at low
speed, meaning riding with relatively high
revs.
Plan rides ahead of time in order to avoid
heavy traffic.
Fuel consumption is also affected by con-
ditions that are out of your control, for in-
stance, poor road condition, hills, riding in
winter.
Observe the following aspects for eco-
nomical fuel consumption:
-The planned inspection intervals must be
closely observed.
-Regular service by a specialized Sachs
dealer will guarantee not only continued
operability, but also economical fuel con-
sumption, low environmental pollution
and a long lifespan.
-Check the tyre pressure every two
weeks.
Low tyre pressure increases rolling resis-
tance. This increases fuel consumption
and tyre wear and adversely affects riding
behaviour.
-Continually check fuel consumption.
-Frequently check the lubricating oil.

RIDING INSTRUCTIONS
Running-in
Running-in instructions for engine
and transmission
CAUTION
Excessive revs while running-in the en-
gine increases the wear of the engine.
Engine faults during the running-in pe-
riod must be immediately reported to a
specialized Sachs dealer.
NOTE
During the running-in period, ride in fre-
quently changing load and rpm ranges. Se-
lect winding and slightly hilly routes. Avoid
constantly low rpm counts and full throttle
under load.
Running-in new tyres
CAUTION
New tyres have a smooth surface. They
must therefore be roughened by care-
fully running them in at various slanted
positions.
Only then will the surface obtain its full
grip!
Running-in new brake linings
WARNING
New brake linings must be run-in and
will not have their full friction power until
after 500 km.
The slightly reduced braking effect can
be compensated for by an increase in
the pressure on the brake lever.
During this period, avoid unnecessary
hard braking actions!
-During the first 500 km:
Less than 1/2 throttle.
-Up to 1.000 km:
Less than 3/4 throttle.
CAUTION
The first inspection must be carried out
immediately after the first 1.000 km.
You can save yourself delays by making
an appointment with a specialized Sachs
dealer in advance.

RIDING INSTRUCTIONS
Braking
Oil and grease
WARNING
The brake discs and linings must be free
of oil and grease!
If the motorcycle is not used for a while,
a rust film may form on the brakes and
thus increase the braking effect. A thick
rust film can cause the brakes to lock
up. When setting out on a ride after a
long lay-up period, carefully operate the
brakes several times until they work nor-
mally.
NOTE
Make sure you practice braking for emer-
gency situations, but do so where you will
not pose a risk to yourself or others (e.g. a
deserted parking area).
WARNING
Operate the brakes to grind off the salt
deposited on the brake discs.
Dirty brakes
When riding on dirty streets, the braking
effect can be delayed due to dirty brake
discs and linings.
WARNING
Operate the brakes until they are
clean. Lining wear is increased by dirty
brakes!
Wet brakes
Washing the motorcycle or riding through
water or rain can delay the braking effect
due to wet or (in winter) ice-covered brake
discs and linings.
WARNING
The brakes must first be operated until
they are dry
Salt film on the brakes
When riding on salted streets without brak-
ing for a while, the full braking effect may
be delayed.
