DRIVING INSTRUCTIONS

Instructions for initial operation

– Verify that your KTM dealer performed the PREPARATION

OF VEHICLE jobs (see Customer Service Manual).

– Read the entire manual carefully before your first drive.
– Familiarize yourself with the operating elements.
– Adjust the foot brake pedal and the hand brake lever to the

most comfortable positions for you.

– Get used to handling the motorcycle on an empty car park,

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.

– Hold the handlebar with both hands and leave your feet on

the foot rests while driving.

– Remove your foot from the foot brake pedal when you are

not braking. If the foot brake pedal is not released the brake
pads rub continuously and the braking system is overheated.

– You may only be accompanied by a passenger if your

motorcycle is fitted and registered for such purposes. The
passenger must hold on to the supporting strap or the driver
and keep his feet on the passenger footrests throughout the
ride.

– 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.

– New tires have a smooth surface and must be run in. For

this purpose, carefully ride the motorcycle at moderate
speed, tilting the vehicle at different angles so that the sur-
face is evenly roughened. Tires will not display their full grip
characteristics before they are properly run in.

– 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 and passenger with protective clothing and helmet.

– Pay attention to running in instructions.

Running in 

Even finely machined surfaces of engine parts have rougher
surfaces than parts that slide on each other for a long time.
Therefore, every engine must be run in. For this reason, do not
demand maximum performance from the engine for the first
100 kilometers. The vehicle must be run in at low, changing
performance level for the first 1000 KM (620 miles). The maxi-
mum number of revolutions per minute must not go exceed
4800 rpm. Once you have run your engine in for 1000 km
(620 mi), you may push it to its 8500 rpm limit , i.e. up to the
red zone indicated in the tachometer. Exceeding the above
listed rotations as well as pushing high rpm when the engine is
cold will have an adverse effect on the life of your engine.

Check the following before each start

When you start off, the motorcycle must be in a perfect tech-
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.

3 CHAIN

A loose chain can fall off; an extremely worn chain can tear,
and insufficient lubrication can result in unnecessary wear to
the chain and rear sprockets.

4 TIRES

Check for damaged tires. Tires showing cuts or dents must
be replaced. The tread depth must comply with the legal
regulations. Also check the air pressure. Insufficient tread
and incorrect air pressure reduce the driving performance.

5 BRAKES

Check correct functioning of the braking system. Check for
sufficient brake fluid in the reservoir. If the level of brake
fluid falls below the minimum value, this indicates a leak in
the braking system or completely worn out brake pads.
Arrange for the braking system to be checked by a KTM
specialist garage, as complete failure of the braking system
can be expected.
Also check the state of the brake hoses and the thickness of
the brake linings. Brake linings measured at their thinnest
point should not be less than 1 mm since extremely worn
linings can lead to brake failure.

6 CABLES

Check correct setting and easy running of all control cables.

7 COOLING LIQUID

Check the level of cooling liquid when the engine is cold.

8 ELECTRICAL SYSTEM

Check correct functioning of headlamps, parking light, tail-
light, brake light, flashers, indicator lamps and horn while
the engine is running.

9 LUGGAGE

If you are taking luggage with you, check that this is secu-
rely fastened.
