Instructions for initial operation
– Verify that your KTM dealer performed the PREPARATION
OF VEHICLE jobs (see Customer Service Manual).
– Read these operating instructions carefully before your first
ride.
– Familiarize yourself with the operating elements.
– Adjust the hand brake lever and foot brake lever to the
most comfortable positions for you.
– Get used to handling the motorcycle on an empty parking
lot or open space, before starting on a longer drive. Also try
to drive as slowly as possible and in standing position, to
improve your feeling for the vehicle.
– Do not drive along off-road tracks which go beyond your
abitily and experience.
– Hold the handlebars with both hands and leave your feet on
the foot rests while driving.
–
Remove your foot from the foot brake lever when you
are not braking. If the foot brake lever is not released the
brake pads rub continuously and the braking system is
overheated.
– Do not make any alterations to the motorcycle and always
use ORIGINAL KTM SPARE PARTS. Spare parts from other
manufacturers can impair the safety of the motorcycle.
– Motorcycles are sensitive to alterations in the distribution of
weight. If you are taking luggage with you, this should be
secured as close as possible to the middle of the vehicle; dis-
tribute the weight evenly between the front and rear wheel.
Never exceed the maximum permissible laden weight and
the axle weights. The maximum permissible laden weight is
made up of the following components:
– Motorcycle ready for operation and tank full
– Luggage
–
Driver with protective clothing and helmet.
– Pay attention to running-in procedure.
Running in the LC-4 models
Even very precisely machined sections of engine components
have rougher surfaces than components which have been sli-
ding across one another for quite some time. Therefore, every
engine needs to be broken in. For this reason, during its first
1000 kilometers (620 miles) the engine must not be revved up
to its performance limits. The engine speed of 4800 r.p.m.
must not be exceeded during the first 1000 kilometers (620
miles). During this break-in time, you should ride your
motorcycle in different conditions (roads, easy off-road ter-
rain). The following table shows you the maximum velocity
values in the different gears at 4800 r.p.m. as based on the
rear wheel transmission ratio of your motorcycle.
NOTE:
DURING THE STAGE OF RUNNING THE ENGINE IN, THAT IS THE FIRST
1000 KM (620 MILES), THE ENGINE OIL USED SHOULD BE OF A MINE-
RAL OIL FORMULA. THIS ALSO APPLIES IF THE ENGINE HAS BEEN REPAIRED.
Check the following before each start
When you start off, the motorcycle must be in perfect mecha-
nical condition. For safety reasons, you should make a habit of
performing an overall check of your motorcycle before each
start.
The following checks should be performed:
1 CHECK THE OIL LEVEL
Insufficient oil results in premature wear and consequently
to engine damage.
2 FUEL
Check that there is sufficient fuel in the tank; when closing
the filler cap, check that the tank venting hose is free of
kinks.
3 CHAIN
A loose chain can fall from the chain wheels; an extremely
worn chain can tear, and insufficient lubrication can result in
unnecessary wear to the chain and chain wheels.
4 TIRES
Check for damaged tires. Tires showing cuts or dents must be
replaced. The tread depth must comply with the legal regula-
tions. Also check the air pressure. Insufficient tread and incor-
rect air pressure deteriorate the driving performance.
5 BRAKES
Check correct functioning of the braking system. Check for
sufficient brake fluid in the reservoir. The reservoirs have
been designed in such a way that brake fluid does not need
to be refilled even when the brake pads are worn. If the
level of brake fluid falls below the minimum value, this indi-
cates a leak in the braking system or completely worn out
brake pads. Arrange for the braking system to be checked
by a KTM specialist, as complete failure of the braking
system can be avoided.
Also check the state of the brake hose and the thickness of
the brake linings.
Check free travel at hand brake lever and foot brake lever.
6 CABLES
Check correct setting and easy running of all control cables.
7 COOLING FLUID
Check the level of cooling fluid when the engine is cold.
8 ELECTRICAL SYSTEM
Check correct functioning of headlamps, tail-lights, brake
lights, indicators, control lamps and horn while the engine is
running.
9 LUGGAGE
If you are taking luggage with you, check that this is
securely fastened.

–A
LWAYS TURN ON THE LIGHT TO MAKE SURE THAT OTHER DRIVERS
BECOME AWARE OF YOU AS EARLY AS POSSIBLE.
–O
NLY USE ACCESSORIES THAT HAVE BEEN RELEASED BY KTM. FOR
EXAMPLE, FRONT PANELLING CAN IMPAIR THE DRIVING PROPERTIES OF
THE MOTORCYCLE. CASES, EXTRA TANKS ETC. CAN ALTER THE WEIGHT
DISTRIBUTION AND THUS ALSO IMPAIR THE VEHICLES DRIVING
PROPERTIES.
–T
HE FRONT AND REAR WHEEL ARE ALLOWED TO BE FITTED ONLY WITH
TIRES THAT HAVE THE SAME PROFILE TYPE.
WARNING
IMPORTANT INSTRUCTIONS FOR THE SUPER COMPETI-
TION MODELS:
