DRIVING INSTRUCTIONS
»
– 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 GIV-
ING IT A CHANCE TO WARM UP. AFTER THAT NO FURTHER PRE-
CAUTIONS IN THIS RESPECT NEED BE TAKEN. THE ENGINE HAS
REACHED ITS OPERATING TEMPERATURE AS SOON AS THE RADI-
ATORS BECOME WARM.
– 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.
– LONG WHEELIES LEAD TO A DROP IN THE OIL PRESSURE WHICH
CAN LEAD TO ENGINE DAMAGE.
– NEVER USE YOUR MOTORCYCLE WITHOUT AN AIR FILTER.
OTHERWISE DUST AND DIRT MAY ENTER THE ENGINE AND CAUSE
INCREASED WEAR.
– THE RED COOLANT WARNING LAMP LIGHTS UP WHEN THE COOLANT
TEMPERATURE HAS REACHED 120°C.
POSSIBLE CAUSES FOR THE INCREASE IN TEMPERATURE:
-LOW DRIVING VELOCITY AND HIGH LOAD SITUATION IN HIGH AIR
TEMPERATURES
-LEVEL OF COOLANT IN THE SYSTEM IS INSUFFICIENT
-FAN AT LEFT RADIATOR IS NOT RUNNING
-IMPROPER USE OF THE CLUTCH WHILE DRIVING AT LOW VELOC-
ITIES
PLACE A CLOTH ON THE RADIATOR CAP. OPEN THE CAP SLOWLY,
SO THE EXCESS PRESSURE IN THE COOLING SYSTEM CAN ESCAPE.
- CAUTION SCALDING HAZARD! - AND CHECK THE COOLING LIQ-
UID LEVEL.
DO NOT DRIVE ON, UNTIL THERE IS SUFFICIENT LIQUID IN THE
COLING SYSTEM. HOWEVER, CALL ON ONE OF KTM’S DEALERS
AS SOON AS POSSIBLE IN ORDER TO HAVE THE DEFECT REME-
DIED.
– IF ANY ABNORMAL VIBRATIONS OCCUR WHILE DRIVING, CHECK
THAT THE ENGINE FASTENING BOLTS ARE TIGHT.
– IN THE EVENT THAT, WHILE RIDING ON YOUR MOTORCYCLE, YOU
NOTICE ANY UNUSUAL OPERATION-RELATED NOISE, STOP IMME-
DIATELY, TURN THE ENGINE OFF, AND CONTACT AN AUTHORIZED
KTM DEALER.
Braking
Close throttle and apply the hand and foot brakes at the same time.
When driving on sandy, wet or slippery ground use mainly the rear
wheel brake. Always brake with feeling, blocking wheels can cause
you to skid or fall. Also change down to lower gears depending on
your speed.
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.
– ON SALT-SPRAYED OR DIRTY ROADS BRAKE ACTION MAY BE
DELAYED AS WELL. FIRST, THE BRAKES MUST BE BRAKED CLEAN.
– WHEN YOU BRAKE, THE BRAKE DISCS, BRAKE PADS, BRAKE
CALIPER AND BRAKE FLUID HEAT UP. THE HOTTER THESE PARTS
GET, THE WEAKER THE BRAKING EFFECT. IN EXTREME CASES,
THE ENTIRE BRAKING SYSTEM CAN FAIL.
– DIRTY BRAKE DISCS CAUSE INCREASED TEAR OF BRAKE PADS
AND BRAKE DISCS.
Kickstart instructions
Be sure to kick up the side stand before you start the engine to
avoid any damage.
Start as described above, then push the kickstarter hard ALL THE
WAY.
– WHEN STARTING THE ENGINE, MAKE SURE THAT YOU ALWAYS WEAR
STURDY MOTORCYCLING BOOTS IN ORDER TO AVOID INJURY. YOU
MIGHT SLIDE OFF THE KICKSTARTER, OR THE ENGINE MAY CAUSE
THE KICKSTARTER TO RECOIL, THEREBY CAUSING INJURIES TO
FOOT AND LEG.
– ALWAYS KICK THE KICKSTARTER BRISKLY ALL THE WAY AND,
WHILE DOING SO, NEVER OPEN THE THROTTLE. KICKSTARTING
WITH INSUFFICIENT MOMENTUM AND AN OPENED THROTTLE
LEVER INCREASES THE DANGER OF A POSSIBLE RECOIL.
BEFORE YOU ACTUATE THE KICKSTARTER, BE SURE TO KICK UP THE
SIDE STAND.
Starting off
Pull the clutch lever. Put the engine into first gear, slowly release
the clutch lever and open throttle at the same time.
BEFORE YOU START OFF, CHECK THAT THE MAIN STAND HAS BEEN
SWUNG UP FULLY. IF THE STAND DRAGS ON THE GROUND, THE
MOTORCYCLE CAN GO OUT OF CONTROL.
Shifting/Riding
You are now in first gear, refered to as the drive or uphill gear.
Depending on the conditions (traffic, road gradient, etc.), you can
shift to a higher gear. Close throttle, at the same time pull clutch
lever and shift to the next higher gear. Let clutch lever go again
and open throttle. If you turned on the choke, make sure you turn
it off again as soon as engine is warm.
When you reach full speed through turning the throttle grip all the
way, turn throttle back to 3/4; the speed hardly decreases although
the engine will use less gas. Never open the throttle wider than
the engine can handle. Excessive turning of the throttle grip will
increase full consumption.
By shifting down, use the brakes if necessary and close throttle at
the same time. Pull clutch lever and shift down to the next gear.
Let clutch lever go slowely and open throttle or shift down again.
If, for example, the engine stalls at an intersection, simply pull
the clutch lever and start. You do not need to shift into the neu-
tral position.
– AVOID ABRUPT LOAD CHANGES WHILE RIDING AROUND BENDS
AND ON WET OR SLIPPERY GROUND. OTHERWISE YOU MIGHT EAS-
ILY LOSE CONTROL OVER YOUR MOTORCYCLE.
– WHILE RIDING YOUR MOTORCYCLE, NEVER SWITCH THE IGNITION
LOCK TO POSITIONS AND .
– DO NOT TRY TO CHANGE THE SETTINGS WHILE DRIVING. YOUR
ATTENTION WILL BE DISTRACTED FROM THE TRAFFIC AND MAY
CAUSE YOU TO LOSE CONTROL OF YOUR MOTORCYCLE.
– AFTER FALLING WITH THE MOTORCYCLE, CHECK ALL FUNCTIONS
THOROUGHLY BEFORE STARTING UP OPERATIONS AGAIN.
