Chain maintenance
For long chain life, good maintenance is very important. 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).

Also check sprockets and chain guides for wear, and replace if necessary.
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 informations about KTM disc brakes
BRAKE CALIPERS:
The brake calipers of this series “float“. This means that the brake calipers
are not solidly attached to the caliper support. Thus, the brake pads are
always in optimum contact with the brake disc.
BRAKE PADS:
The motorcycles are delivered with organic brake pads and have also been
type-coded with these pads. Said pads are suitable for almost the entire
range of application of these motorcycles.
It is only for competitive racing in extremely dirty conditions (e.g., water in
combination with sand and mud) that we recommend brake pads that
have sintered linings. However, take notice of the fact that brake pads with
sintered linings have not been type-coded! Besides, they may cause greater
wear on the brake discs.
BRAKE FLUID RESERVOIRS:
The brake fluid reservoirs on the 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 either the brake system has a leak or the brake pads are completely
worn down.
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.
