    Special stands are required to dismount the wheels to make sure the motorcycle is securely fixed. The stands shown in the illustration can be found in the KTM Power Parts catalog. Mount the rear stand. Make sure the stand rests on solid ground and is correctly mounted.

  • Page 52: Tires, Air Pressure

    – IF 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 WHEEL SPINDLE MAY LEAD TO AN UNSTABLE DRIVING BEHAVIOR OF YOUR MOTORCYCLE.

  • Page 53: Battery

    – Tire type and size can be found in the technical specifications and in the homologation certificate. – For the type of tires authorized by KTM, contact your authorized KTM dealer or special- ized tire dealer. – Tire condition has to be checked every time you want to ride your motorcycle. Before leaving check for punctures and nails or other sharp objects that might have become embedded in the tire.

  • Page 54: Removing And Remounting The Battery

    NEVER DISCONNECT THE BATTERY WHILE THE ENGINE IS RUNNING. THIS WILL DESTROY THE RECTIFIER-REGULATOR. STORAGE: If the motorcycle is being immobilized for longer periods of time, remove and charge the battery. Storage temperature 0 - 35°C (32 - 95°F), avoid direct sunlight. Charge the battery every 3 months.

  • Page 55: Charging The Battery

    Always use special charging devices to charge maintenance-free batteries, e.g. the KTM charg- ing device (item no. 58429074000). You can also use this charging device to test the off- load voltage and startability of the battery and generator.

  • Page 56: Main Fuse

    Pull the connector [1] out of the bracket, remove the cap [2] and check the main fuse [3]. A spare fuse [4] (30 amperes)is also plugged into the bracket. Always replace blown fuses with an equivalent fuse. Visit an authorized KTM workshop if a new fuse blows again after it is inserted.

  • Page 57: Fuses For Individual Power Consumers

    Replace a blown fuse only with an equivalent one. If a new fuse that has just been set in gets blown again, you are strongly advised to have it inspected by a KTM dealer. UNDER NO CIRCUMSTANCES IS A STRONGER FUSE ALLOWED TO BE SET IN OR A FUSE ALLOWED TO BE “REPAIRED”.

  • Page 58: Replacing The Headlight Lamp

    Attach the retaining clip, connect the connector to the bulb and mount the rubber cap. BULB FOR THE PARKING LIGHT: Since a number of parts need to be removed to replace the parking light bulb, we recom- mend that you have the lamp replaced at an authorized KTM workshop.

  • Page 59: Adjusting The Headlight Range

    Make a mark on a light colored wall behind a horizontal surface, at the height correspon- ding to the center of the headlight. Position your motorcycle 5 meters (16.4 ft) from the wall in a fully loaded condition (baggage, driver, passenger) and switch on the low beam.

  • Page 60: Replacing The Flasher Bulbs

    Replacing the flasher bulbs Remove the screw on the back of the turn signal, carefully fold the lens [2] towards the motorcycle and remove.

  • Page 63: Checking The Cooling Liquid Level In The Radiator

    If any cooling liquid is missing, the cooling system is probably leaking. Have the cooling system checked at an authorized KTM workshop. IF POSSIBLE, CHECK THE COOLING LIQUID LEVEL WHEN THE ENGINE IS COLD. IF YOU NEED TO REMOVE THE RADIATOR CAP WHEN THE ENGINE IS HOT, HOLD THE CAP WITH A CLOTH AND OPEN SLOWLY, ALLOWING ANY EXCESS PRESSURE TO ESCAPE (DANGER OF SCALDING).
  • Page 64 MAINTENANCE WORK ON CHASSIS AND ENGINE Remove the bleeder screw [5] on the left side of the radiator. To completely bleed the cooling system, the motorcycle must be raised approx. 50 cm (20 in) in the front. Add cooling liquid until it runs out of the vent holes without bubbles and immediately mount the screw to prevent air from entering the radiator.

  • Page 69: Changing Engine Oil/Filter

    Since many parts must be demounted for an oil change, we recommend having the engine oil changed by an authorized KTM workshop. During the guaranty period, the oil change must be performed by an authorized KTM mechanic. Otherwise, the guarantee will become void.
  • Page 70 » MAINTENANCE WORK ON CHASSIS AND ENGINE Remove the drain plug [6] on the oil tank and allow the oil to drain into a receptacle. Remove the screws [7] and tilt the oil return valve [8] to the side. Carefully pull the oil screen [9] out of the oil tank. Thoroughly clean the drain plugs, the cover and both oil screens.
  • Page 71 Insert a new oil filter [3] in the engine case, grease the O-ring and mount the oil filter cover together with the O-ring. Tighten the screws to 6 Nm. ONLY USE ORIGINAL KTM OIL FILTERS. THE ENGINE CAN BE DAMAGED IF OTHER FILTERS ARE USED.
  • Page 72 » MAINTENANCE WORK ON CHASSIS AND ENGINE Remove the right spoiler (see Refilling the engine oil) and unscrew the plug [6]. Add 2.5 liters (0.7 USgal) of fully synthetic engine oil meeting the JASO MA standard (e.g. Motorex Power Synt 4T) and remount the plug. Start the engine and allow to run warm in neutral until 4 bars on the temperature indicator light up.
