STEERING
Check and adjust ➝
B
Check the steering components regularly according to
the above-mentioned intervals.
If it is necessary to carry out adjustments, operate as
described in chapter F "Suspension and wheels".
TRANSMISSION CHAIN
Check ➝
At the pre-delivery, at the first 1000
kilometres and then every 6000 kilo-
metres
Substitute ➝
Every 6000 kilometres (Brutale 750
ORO)
Every 12000 kilometres (Brutale 750
S - 910 S - 910 R - 989 R - 1078 RR)
Place the motorcycle on the rear stand.
The chain tension check should be effectuated with the
motorcycle having a static set-up quota equal to the fol-
lowing standard values (see chapter F "Suspension and
wheels"):
BRUTALE 750 ORO - 750 S (MY 03): 190 mm
BRUTALE 750 S (MY 04):
BRUTALE 910 S - 910 R - 989 R - 1078 RR: 200 mm
The clearance "h" between the axis of symmetry of the
chain and the chain cover should be equal to the follow-
ing values as shown in the figure.
BRUTALE 750 ORO - 750 S (MY 03): h = 6 mm
BRUTALE 750 S (MY 04):
BRUTALE 910 S - 910 R - 989 R - 1078 RR: h = 9 mm
Manually rotate the rear wheel and effectuate this check
at different points along the chain.
As the wheel is turned, the play should remain virtual-
ly the same. If, on the other hand, the play on the chain
varies considerably, it means that some of the links are
flattened, jammed or elongated.
Visually check the transmission chain for the following
defects:
• Slack pins
• Damaged rollers
• Dry and rusty links
• Bent or seized links
The chain must be substituted if any one of these defects
is found.
When substituting the transmission chain, substitute also
the crown and pinion wheel.
For the substitution of the chain, pinion, crown wheel and
to check the wear of the chain guide, follow the sequence
described in chapter F "Suspension and wheels".
