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. Secure the screws of the
caliper support with Loctite 243 and tighten to 25 Nm (19 ft.lb).
BRAKE PADS:
The brake pads are fitted with TOSHIBA TT 2701 sintered lining at the front
and TOSHIBA H 38 sintered lining at the back. These linings provide an
16 17 18
optimal combination of dosing, brake performance and lifecycle. The lining
type is stated on the back of the brake pad and also recorded in the homo-
logation papers.
Other brake pads are available for competition sports.
FRONT: TOSHIBA H 38 (SINTERED) – harder to dose, good brake per-

DOT REAR:

BRAKE DISCS:
Due to wear, the thickness of the brake disc in the area of the contact
face
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
the contact face. Check wear in several locations.

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
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 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
A
may use DOT 4 brake fluid. However, you should replace it as soon as
possible by DOT 5.1.
B
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!
