Checking Drive Chain Tension - Ducati DESMOSEDICI RR Owner's Manual

Checking drive chain tension

Important
Have chain tension adjusted by a Dealer or Authorised
Workshop.
With the motorcycle on the side stand, push down on the
lower stretch of chain with one finger, release the chain and
measure the distance between the aluminium section of the
swinging arm and chain pin centres. Distance should be
E
between 52 ÷ 54 mm.
Adjust chain tension as follows.
Loosen rear wheel shaft nut (1, fig. 69.2).
Tighten screw (2) (clockwise) on either sides of the
swingarm by equal amounts to increase chain tension or
loosen them to slacken chain. In this last instance, it is
necessary to push the wheel forward.
Ensure that reference marks (A) on either sides of the
swingarm match; in this way wheel alignment is guaranteed.
Warning
Correct tightening of tensioner check nuts (1, fig. 69.2)
is critical to rider safety.
Important
Improper chain tension will lead to early wear of
transmission parts.
