Chain wear

In order to check the chain wear, regard the following indications:
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:
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
16 17 18
combination with sand and mud) that we recommend brake pads that have
sintered linings. However, take notice of the fact that brake pads with sinte-
red linings have not been type-coded! Besides, they may cause greater wear
on the brake discs.
BRAKE FLUID RESERVOIRS:
The brake fluid reservoirs on front and rear wheel brakes have been desi-
gned in such a way that even if the brake pads are worn it is not necessary
to top up the brake fluid. If the brake fluid level drops below the minimum
DOT
level either the brake system has a leak or the brake pads are completely
worn.

In this case, consult an authorized KTM dealer immediately.
BRAKE FLUID:
KTM fills the brake system with "Shell Advance Brake DOT 5.1", one of the
best brake fluids 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.

Adjusting of free travel at the hand brake lever

Free travel at the hand brake lever may be readjusted by using adjustment
