malfunction in the ABS. 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 warning lamp may also light up if the rotating speeds of
the front and rear wheels differ greatly under extreme riding con-
ditions, for example when making "wheelies" or if the rear wheel
spins. This causes the ABS to switch off.
To reactivate the ABS, stop the vehicle and switch off the ignition.
The ABS is reactivated when the vehicle is switched on again. The
ABS warning lamp goes out after starting off.
MSC
The MSC is a supplementary function for the ABS that can prevent
blocking and slipping of the wheels during braking when the vehi-
cle is inclined (riding in curves) within the physical limitations.
Due to the inertial measurement unit, the ABS control is depen-
dent on the angle of inclination and pitch.
Info
The MSC is only active in Road ABS mode.
14.2 Checking the brake discs
Warning
Danger of accidents Worn-out brake discs reduce the braking effect.
– Make sure that worn-out brake discs are replaced immediately. (Your authorized KTM workshop will
be glad to help.)

– Check the front and rear brake disc thickness at multiple
points for the dimension
A
.
Info
Wear will reduce the thickness of the brake disc at con-
tact surface

of the brake linings.
Brake discs - wear limit
front 4.5 mm (0.177 in)
rear 4.5 mm (0.177 in)
» If the brake disc thickness is less than the specified value:
– Change the front brake discs.
– Change the rear brake disc.
– Check the front and rear brake discs for damage, cracking, and
deformation.
» If the brake disc exhibits damage, cracking, or deforma-
tion:
– Change the front brake discs.
– Change the rear brake disc.
