Brake fluid reservoir

8.53
Warning
Danger of accidents Brake 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.

Brake calipers

The brake calipers of this series are "floating", which means that they are not fixed to the brake caliper support.
The lateral compensation ensures an optimal position of the brake pad in relation to the brake disc.

Checking brake discs
