Warning
Danger of accidentsBrake system failure.
If the brake fluid level falls below the MIN mark, this indicates a leakage in the brake system or worn-out brake linings.
Have the brake system checked in an authorized KTM workshop, and do not ride any further.
The brake fluid reservoirs of the front and rear brakes are dimensioned so that they do not need topping up with brake fluid even if the
brake linings are worn.
