ENGLISH 24 WARNING MAINTENANCE AND ADJUSTING WORK MARKED WITH AN ASTERISK (*) REQUIRES EXPERT SKILLS AND TECHNICAL KNOW-HOW. FOR YOUR OWN SAFETY, ALWAYS HAVE SUCH WORK PERFORMED BY A SPECIALIZED KTM DEALER WHERE YOUR MOTORCYCLE WILL BE OPTIMALLY SERVICED BY APPROPRIATELY QUALIFIED, SKILLED STAFF.
ENGLISH 25 How to change the handlebar position The handlebar position can be readjusted by 22 mm. Thus, you can put the handlebar in the position that is the most convenient for you. The upper tri- ple clamp 1 includes 2 bores arranged at a distance of 15 mm (0.
ENGLISH 26 Basic suspension setup for the weight of the driver To achieve maximum handling performance and to prevent the fork, shock absorber, swing arm and frame from being damaged, the basic setup of the suspension components must be suitable for your weight.
ENGLISH 27 According to our experience, the damping rate of the compression stage can remain unchanged. The damping rate of the rebound stage can be reduced by a few clicks for a softer spring or increased by a few clicks for a harder spring.
ENGLISH 28 Adjusting the spring preload on the fork (SX) The spring preload on the SX models can be adjusted (changed) by 10 mm by turning adjusting screw 1 . Turning in a clockwise direction will increase the prestress, turning in a counterclockwise direction will decrease the prestress.
ENGLISH 29 Check chain tension To check the chain tension, park the motorcycle. Press the chain upward at the end of the chain sliding component. The distance between the chain and the swing arm should be approx. 15 mm (0.6 in). In the course of this procedure, the upper chain portion A must be taut (see drawing).
ENGLISH 30 Chain maintenance For long chain life, good maintenance is very important. X-ring chains require only modest maintenance. The best way is to use lots of water, but never use brushes or solvents. After letting the chain dry, you can use a special X-ring chain spray (Shell Advance Bio Chain).
ENGLISH 31 General information about KTM disc brakes BRAKE CALIPERS: The brake calipers of this series use a ”floating” mount. This means that the brake calipers are not solidly attached to the caliper support, which enables them to ”float” for maximum braking contact.
ENGLISH 32 Adjusting the free travel at the hand brake lever Free travel at the hand brake lever may be readjusted by using adjustment screw 1 . In this way, the position of the point of pressure (i.e. the resis- tance you feel on the hand brake lever when the brake pads are pressed against the brake disc) can be adjusted for any hand size.
ENGLISH 33 Replacing the front brake pads * Press the brake caliper toward the brake disk, to put the brake piston in its basic position. Remove clips 1 and pull out bolt 2 . Remove brake pads from the brake caliper. Clean the brake caliper and the brake caliper support with compressed air.
ENGLISH 34 Checking the rear brake pads The brake pads can be inspected from the rear. The thickness of the linings may not be less than 1 mm (0.04 in). WARNING A T THEIR MOST WORN POINT BRAKE PAD LININGS SHOULD NOT BE THINNER THAN 1 MM , OTHERWISE THEY COULD LEAD TO BRAKE FAILURE .
ENGLISH 35 WARNING –I F YOU DON ’ T HAPPEN TO HAVE A TORQUE WRENCH AT HAND , MAKE SURE YOU HAVE THE TIGHTENING TORQUE CORRECTED BY A KTM DEALER AS SOON AS POSSIBLE . A LOOSE AXLE MAY LEAD TO AN UNSTABLE DRIVING BEHAVIOR OF YOUR MOTORCYCLE .
ENGLISH 36 Ti res, air pressure Tire type, tire condition, and air pressure level affect the way your motorcy- cle rides and must therefore be checked whenever you are getting ready to go anywhere on your motorcycle.
ENGLISH 37 Setting the clock To set the clock, switch the ignition off and select the SPEED/CLK mode. Press and hold the MODE button for 3 seconds. The blinking digits can be changed using the + and – buttons. Press the MODE button to move to the next digit.
ENGLISH 38 Check/set distance of the magnetic sensor The distance between the magnet 2 and the sensor 1 must be 2-4 mm, otherwise malfunctions on the speedometer might occur. This distance can be corrected by screwing the sensor 1 in or off. mm x 3,14 KMH: WS = mm x 3.
ENGLISH 39 Cooling system The water pump in the engine circulates the cooling liquid. However, the cooling liquid can only circulate properly if the cooling circuit contains no air bubbles. Bleeding of the cooling system is therefore required a) after adding more than 0.
ENGLISH 40 Refilling/Bleeding the cooling system The cooling system must be bled as described below after draining the cooling liquid or after adding more than 0.25 l (0.06 US gallons) cooling liquid. Make sure that the drain screw 1 is fastened. Pour approx.
ENGLISH 41 Changing the original position of the clutch lever The adjusting screw 1 can be used for individual adjustment of the original position of the clutch lever, thus allowing adjustment to an optimal position for every hand size. Turning the adjusting screw clockwise reduces the distance between the clutch lever and the handlebar.
ENGLISH 42 Cleaning the spark arrestor (EXC USA) * With these models, the spark arrestor is part of the exhaust silencer. Clean it every 4000 km (2500 miles) to guarantee proper functioning. Also clean the spark arrestor when replacing the glassfiber yarn filling.
ENGLISH 43 Opening up B Engine behavior when the throttle opens. The idle jet and the shape of the throttle valve influences this range. If, despite good idling-speed and part- throttle setting, the e.
ENGLISH 44 Check transmission oil level (125/200) In order to check the transmission oil level the control screw 1 on the clutch cover is to be removed. Oil should just barely escape from the inspection opening when the motorcycle is in an upright position.
ENGLISH 45 Should you wish to make a pause over a longer space of time, please observe the following instructions: – Clean motorcycle thoroughly (see chapter: CLEANING) – Change engine oil (old engine oil contains aggressive contaminants). – Check antifreeze and amount of cooling liquid.
