Warning Danger of accidents
  • Changes to the vehicle impair the function of the ABS.
  • Do not make any changes to the suspension travel.
  • Only use spare parts on the brake system which have been approved and recommended by KTM.
  • Only use tires/wheels approved by KTM with the corresponding speed index.
  • Maintain the specified tire air pressure.
  • Service work and repairs must be performed professionally.(Your authorized KTM workshop will be glad to help).

    The ABS is a safety system that prevents locking of the wheels when driving straight ahead without the influence of lateral forces.

    Warning Danger of accidents Driving aids can only prevent a rollover within the physical limitations. It is not always possible to compensate for extreme riding situations, for example with luggage loaded with a high center of gravity, varying road surfaces, steep descents or full braking without disengaging the gear. – Adapt your riding style to the road conditions and your driving ability

    The ABS operates front brake circuit. During nor- mal operation, the brake system operates like a conventional brake system without ABS. When the ABS control unit detects a locking tendency in a wheel, ABS begins regulating the brake front pressure.

    The regulating process causes a slight pulsing of the hand brake lever. The ABS indicator lamp 3 must light up after the ignition is switched on and go out after starting off. If it does not go out after starting off or if it lights up while riding, this indicates a fault in the ABS system. In this case, the ABS is no longer enabled and the wheels may lock during braking. The brake system itself stays functional; only ABS control is not available. The ABS indicator lamp may also light up if the rotating speeds of the front and rear wheels differ greatly under extreme riding conditions, for example when making "wheelies" or if the rear wheel spins. This causes the ABS to switch off. To reactivate the ABS, the vehicle must be stopped and the ignition switched off. The ABS is reactivated when the vehicle is switched on again. The ABS indicator lamp goes out when you start off. The ABS deactivation function is not absent in the model. The ABS deactivation button is dummy in Duke 125.

    Warning
    Danger of accidents functional limitation of ABS.The rear wheel may only be spun with the front brake applied (born out) if the ABS is switched off. If the vehicle has been modified, such as shortened or lengthened spring deflection, different rim diameter, different tires, the wrong tire air pressure, different brake linings, etc., the ABS will not functioning optimally. Optimal functioning of the ABS is only ensure if the brake system only contains spare parts and tires that have been approved and / or recommended by KTM.Service work and repairs must be performed properly. (Your authorized KTM workshop will be glad to help).

    Warning
    Danger of accidentsRolling over the vehicle.It is not always possible to prevent rolling over the vehicle in extreme riding situation (e.g. luggage loaded with a high center of gravity, varying road surfaces, steep descent, full braking disengaging the gear). Adapt your riding style to the road conditions & your riding ability.

    Warning
    Danger of accidents Failure of the brake system.- If the brake fluid level falls below the MIN mark, this indicates the leakage in the brake system or worn-out brake linings. Check the brake system and do not continue riding.

    Warning
    Skin Irritation Brake fluid can cause skin irritation on contact. Avoid contact with skin and eyes, and keep out of the reach of children. - Wear suitable protective clothing and goggles.If brake fluid comes into contact with the eyes, flush the eyes thoroughly with water and consult a physician immediately.

    Warning
    Danger of accidents Reduced braking effect caused by old brake fluid. Change the brake fluid of the front brake according to the service schedule. (Your authorized KTM workshop will be glad to help).

    Warning
    Environmental hazard Hazardous substances cause environmental damage. Oil, grease, filters, fuel, cleaners, brake fluid, etc., should be disposed of as stipulated in applicable regulations.

    Info Avoid contact between brake fluid and painted parts. Brake fluid attacks paint! Use only clean brake fluid from a sealed container
  • Move the brake fluid reservoir mounted on the handlebar to a horizontal position.
  • Remove screws 1
    •

    - Position the cover with the membrane. Mount and tighten the screws.

    Info
     Never use DOT 5 brake fluid. It is silicone-based and purple in color. Oil seals and brake lines are not designed for DOT 5 brake fluid.

    Level A5 mm
    Brake fluid DOT 4/ DOT 5.1

    Info
     Clean up overflowed or spilt brake fluid immediately with water. Checking the front brake linings.

    Warning Danger of accidentsReduced braking efficiency caused by worn brake linings. - Change worn brake linings immediately.

    Note
     Danger of accidentsReduced braking efficiency caused by damaged brake discs.
    If the brake linings are not changed in time, the steel brake lining carries grind on the brake disc. The braking effect is greatly reduced and the brake discs are rendered unserviceable. Check the brake linings regularly.

    Check the brake linings for minimum thickness A. Minimum thickness > 1 mm
    If the minimum thickness is less than specified

  • Change the front brake linings.
  • Check the brake linings for damage and cracking. If there is wear or tearing.
  • Change the front brake linings.

    • If the brake fluid level falls below the MIN mark, this indicates a leakage in the brake system or worn-out brake linings. Check the brake system and do not continue riding. (Your authorized KTM workshop will be glad to help).

    Warning
     Danger of accidentsReduced braking effect caused by old brake fluid. Change the brake fluid of the front and rear brake according to the service schedule.

  • Stand the vehicle upright.
  • Check the brake fluid level in the brake fluid reservoir. If the fluid level reaches the MIN mark 1.
  • Add rear brake fluid.
