MAINTENANCE WORK ON CHASSIS AND ENGINE »
Correct chain tension
Loosen collar nut [1], loosen lock nuts [2], and turn right and left adjusting
screws [3] equally far. Tighten lock nuts.
To ensure the correct alignment of the rear wheel, the marks at the left and
right chain adjusters must be positioned identically in relation to the
reference marks [B]. Tighten the counter nut of the adjusting screws.
Clean and grease the adjusting screws regularly (Motorex Long Term Grease
2000). Before tightening the collar nut, verify that the chain adjusters [4] are
sitting close to the adjusting screws and that the rear wheel has been aligned
with the front wheel.
Tighten collar nut [1] to 80 Nm.
– If you don’t happen to have a torque wrench at hand, make sure you have
the tightening torque corrected by a KTM dealer as soon as possible. A
loose axle may lead to an unstable driving behavior of your motorcycle.
– Tighten the collar nut with the required torque.
NOTE:
The large adjusting range of the chain adjusters (32mm) allows you to use
different secondary ratios in combination with the same chain length. The
chain adjusters [4] can be rotated by 180°.
Adapting the chain guide to the number of rear sprocket teeth
NOTE:
The position of the chain guide must be adjusted due to the large number of
rear sprockets available. Up to 44 teeth, insert the retaining screw on the
chain guide in the lower hole [C], from 45 teeth in the upper hole [D].
Loosen both screws on the chain guide and pull the chain guide off the swing
arm. Turn the chain guide over, press out the retaining nut [5] and insert it
in the other hole [6], turning the retaining nut around.
Remount the chain guide and tighten the screws.
