BRAKE FLUID:
KTM fills the brake systems with Motorex Brake Fluid DOT 5.1 brake fluid, one of the best
brake fluids that is currently available. We recommend that you continue to use it. DOT 5.1
brake fluid is based on glycol ether and of an amber color. If you do not have any DOT 5.1
for refilling, you may use DOT 4 brake fluid. However, you should replace it as soon as pos-
sible by DOT 5.1.
Never use DOT 5 braking fluid. It is based on silicone oil and has a purple color. Gaskets
and brake hoses are not compatible with it.
Brake fluid is exposed to a high thermal load and absorbs moisture from the air, which low-
ers the boiling point. The brake fluid should therefore be changed at the prescribed
intervals.
Have the brake fluid for the front and rear brake changed at an authorized KTM workshop
every 2 years.
BRAKE DISCS:
Wear reduces the thickness of the brake disc in the area of contact [1] with the brake pads.
The brake disk should not be thinner than 4.5 mm (0.18 in) at the weakest point [A]. Check
the wear at several points.
Brake disks that are less than 4.5 mm (0.18 in) thick are a safety hazard. Have worn brake
disks replaced immediately.
