Adjusting the basic position of the hand brake lever

The basic position of the hand brake lever can be modified by turning the adjusting screw
[1]. This lets you adapt the position of the pressure point (the resistance you feel on the
hand brake lever when the brake pads are pressed against the brake disk) to fit any hand.
min. 3 mm
AT THE HAND BRAKE LEVER, FREE TRAVEL MUST AT LEAST BE 3 MM (0.12 IN). ONLY THEN MAY
THE PISTON IN THE HAND BRAKE CYLINDER BE MOVED (TO BE RECOGNIZED BY THE GREATER
RESISTANCE OF THE HAND BRAKE LEVER). IF THIS FREE TRAVEL IS NOT PROVIDED, PRESSURE
WILL BUILD UP IN THE BRAKING SYSTEM, AND THE FRONT WHEEL BRAKE MAY FAIL DUE TO
OVERHEATING.

Checking the front brake fluid level

The brake fluid reservoir for the front brake is located on the left side of the handlebar and
has a „MIN" and a „MAX" mark. The brake fluid level may not fall below the „MIN" mark
when the vehicle is parked in a vertical position.
– IF THE BRAKE FLUID LEVEL DROPS BELOW THE MINIMUM EITHER THE BRAKE SYSTEM HAS
A LEAK OR THE BRAKE PADS ARE COMPLETELY WORN DOWN. IN THIS CASE, CONSULT AN
AUTHORIZED KTM DEALER IMMEDIATELY.
– HAVE THE BRAKE FLUID CHANGED AT AN AUTHORIZED KTM WORKSHOP EVERY 2 YEARS.

Refilling front brake fluid *

It is not necessary to refill brake fluid under normal conditions (see General information on
KTM disk brakes).
However, brake fluid must be refilled as soon as the brake fluid level reaches the MIN mark.
Remove the screws [2] and cover [3] with the rubber boot [4]. Move the hand brake cylin-
der in a horizontal position and add DOT 5.1 (Motorex Brake Fluid DOT 5.1). Press the rub-
ber boot together and remount the cover. Wash off any overflowing or spilled brake fluid with
water. Actuate the front brake until you feel the pressure point.
