CHAIN ADJUSTMENT
Chain should be checked, adjusted and lubricated
as per the Maintenance Chart to ensure safety
and prevent excessive wear If the chain becomes
badly worn or is poorly adjusted (ie, if it is too
loose or too taut), it could escape from sprocket
or break
Make sure that the chain features a slack measur-
ing approximately 20 mm, as shown in the name-
plate (1) on swingarm
Preliminary Operations:
-Place the bike on a stand so as to have an ade-
quate working space in the area of the rear wheel
shaft.
-The bike must be firmly fixed and the rear wheel
must be raised and free to rotate.
Procedure:
1. Loosen the lock nuts (3).
2. Loosen the wheel shaft by unscrewing the nut
(2) so that the rear wheel is free to slide in the slot
but without excessive clearance.
3. Operate the adjusters (4) alternately to the right
and to the left and keep visually equal the dis-
tances indicated, until achieving the correct ten-
sioning.
4. Measure the indicated distance (A) with a
gauge and make it identical on both sides, using
the adjusters (4).
5. Check that tensioning is correct in several po-
sitions and that the wheel is free to rotate without
hard spots. If this is not the case, repeat points 3
and 4.
6. Tighten the wheel shaft using the nut (2) (tight-
ening torque 120Nm).
7. Make the adjusters rest on the sliding blocks
using the nut (4) (anticlockwise rotation), slightly
tighten.
8. Tighten the lock nuts (3).
