DRIVING INSTRUCTIONS
– While riding your motorcycle, never switch
the ignition lock to positions
– Do not try to change the settingsof the
combined instrument while driving. Your
attention will be distracted from the traf-
fic and this may cause you to lose con-
trol of your motorcycle.
– The frost symbol * in the combined instru-
ment will start to blink on icy roads. Adapt
your speed to the road and weather con-
ditions.
– The passenger must hold on to the driver
or the holding strap on the seat while rid-
ing and keep his/her feet on the passen-
ger footrests.
– Regularly make sure that the baggage
and cases are tightly fastened.
– After falling with the motorcycle, check
all functions thoroughly before starting up
operations again.
– A bent handlebar must always be replaced.
Never try to straighten the handlebar
because this will cause it to lose its sta-
bility.
– High rpm rates when the engine is cold
have an adverse effect on the life of your
engine. We recommend you run the engine
in a moderate rpm range for a few miles
giving it a chance to warm up. After that
no further precautions in this respect
need be taken. The engine has reached
operating temperature as soon as the 4th
»
bar on the temperature indicator lights up.
– If the red oil pressure warning lamp lights
up while driving, the oil pressure is too
and
.
low to adequately lubricate the engine.
Stop immediately and switch off the
engine. if you continue to drive, engine
damage will occur within a short period
of time. Check the engine oil level or con-
tact an authorized KTM workshop.
– Never have the throttle wide open when
changing down to a lower gear. The engine
will overspeed, damaging the valves. In
addition, the rear wheel blocks so that the
motorcycle can easily get out of control.
– Never use your motorcycle without an air
filter. Otherwise dust and dirt may enter
the engine and cause increased wear.
– Stop immediately if a perceptible power
loss occurs while driving due to a defec-
tive ignition caused by a cylinder misfir-
ing or breaking down. If the unburned
fuel/air mixture reaches the catalytic con-
verter, it will ignite and the resulting heat
will destroy the catalytic converter and the
adjoining components.
– The red coolant warning lamp lights up
when the coolant temperature has reached
120°c (248°F).
Possible causes for the increase in tem-
perature:
– low driving velocity and high load sit-
uation in high air temperatures
– level of coolant in the system is insuf-
ficient
– fan at radiator is not running
– improper use of the clutch while driving
at low velocities
Let the engine cool down. Meanwhile,
check whether any cooling liquid is leak-
ing out of the motorcycle. Check the cool-
ing liquid level in the radiator (not only
in the compensating tank). - CAUTION
SCALDING HAZARD! Do not drive on,
until there is sufficient liquid in the col-
ing system.
– In the event that, while riding on your
motorcycle, you notice any unusual oper-
ation-related noise, stop immediately,
turn the engine off, and contact an author-
ized KTM dealer.

Braking

Close throttle and apply the hand and foot
brakes at the same time. Carefully apply the
brakes on sandy, wet or slippery surfaces.
Always brake with feeling, blocking wheels
can cause you to skid or fall. Also change down
to lower gears depending on your speed.
Always finish braking before you enter a
curve.
When driving downhill, use the braking effect
of the engine. Change down one or two gears
but do not overspeed the engine. In this way,
you will not need to brake so much and the
brakes will not overheat.
– In the rain, or after the motorcycle has
been washed, braking action may be
delayed due to wet brake discs. First, the
brakes must be braked dry.
