Chain maintenance
O-ring chains require only modest maintenance. The best way is to use lots
of water, but never use brushes or solvents. After letting the chain dry, you
can use a special O-ring chain spray (Shell Advance Bio Chain).

Chain wear
In order to check the chain wear, regard the following instructions:
Shift the gear into idling and pull the upper chain strand with approx. 10-15
kilogramm (33 lb) upwards (see figure). Now one can measure a space of
18 chain reels at the lower chain strand. The chain should be replaced at the
latest when a space of 272 mm (10,70 in) is measured. Chains do not
always wear off evenly, therefore repeat the measurement at different pla-
ces on the chain.
NOTE:
If you mount a new chain, the sprockets should also be replaced. New
chains wear faster if used on old used sprockets.
General information about KTM disc brakes
BRAKE CALIPERS:
The brake calipers of this series use a „floating” mount. This means that the
brake calipers are not solidly attached to the caliper support, which enables
them to „float” for maximum braking contact.
BRAKE PADS:
Since KTM motorcycles are mainly designed for races under extremely dirty
conditions (e.g. water in connection with sand and mud), the front wheel is
equipped with brake pads with sintered lining. These linings cover almost
the entire operative range of the motorcycle.
BRAKE DISCS:
Due to wear, the thickness of the brake disc in the area of the contact
face
1
of the brake pads decreases. At their thinnest point
A
, the brake
discs must not be more than 0.40 mm (0,016 in) thinner than the pad's
nominal thickness. Measure the nominal thickness in a location
B
outside
the contact face. Check wear in several locations.

BRAKE FLUID RESERVOIRS:
The brake fluid reservoirs on front and rear wheel brakes have been
designed in such a way that even if the brake pads are worn it is not neces-
sary to top up the brake fluid. If the brake fluid level drops below the mini-
mum level either the brake system has a leak or the brake pads are comple-
tely worn.
In this case, consult an authorized KTM dealer immediately.
BRAKE FLUID:
KTM fills the brake systems with SHELL ADVANCE BRAKE 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
possible by DOT 5.1.
Never use brake fluid DOT 5. The color of this silicon oil-based product is
purple red. The gaskets and brake hoses of KTM motorcycles are not
designed for DOT 5 brake fluid!
