Drive chain slack
The drive chain slack should be checked befo-
re each ride and adjusted if necessary.
To check the drive chain slack
1. After stopping the engine, place the vehi-
cle on a rear stand on a horizontal surface and
with the gear in neutral.
2. Measure the drive chain slack as shown.
3. After running the rear wheel forward occur
else where in the free play chain: it must be
constan.
4. If the drive chain slack is incorrect, adjust it
as follows.
NOTICE
Using the motorcycle with the chain in bad
condition and badly adjusted may cause
accidents.
If you notice any operating anomaly on the
chain, such as excessive or suspicious noi-
ses, or excessive slack, go to an authorised
Benelli workshop.
If you suspect that there is a serious mal-
function with the chain, stop the bike im-
mediately and call your nearest Benelli au-
thorised workshop.
