SCHEDULED MAINTENANCE AND TUNING OPERATIONS

2.35 DRIVE CHAIN

Carefully read 1.3.9 (PRECAUTIONS AND GENERAL
INFORMATION).
DANGER
Riding your motorcycle with a worn-out, improperly
adjusted, dirty, rusty, or otherwise defective chain
can cause the chain to come off of either the front or
rear sprocket, which will jam and cause the rear
wheel to lock. This can lead to loss of control, an
upset, and subsequent accident with serious injury
or even death. Carefully observe the precautions
and instructions given below.
substitute a different type of chain for the original
type of chain.
Check the drive chain every 625 mi (1000 km) and
lubricate if needed. The vehicle is equipped with an
endless chain. There is no master link used.
Type of chain: 525
WARNING
The drive chain is equipped with O-ring gaskets
between the links, to keep the grease inside. Use
utmost care when adjusting, lubricating, washing
and changing the chain. Failure to observe this
warning can destroy your chain.
Place the vehicle on the center stand.
Set the gearshift lever to neutral.
Turn the rear wheel to check the chain play in other
positions.
Visually inspect the chain, making sure that the chain
and sprockets show none of the defects listed below:
- damaged rollers;
- loose pins;
- dry, rusted, crushed or seized links;
- excess wear;
- missing O-rings;
- sprocket teeth excessively worn or damaged.

Never attempt to
A quick check to determine the condition of the chain and
sprockets may be made by grasping the chain and
attempting to pull it away from the rear sprocket. If you
can pull the chain away from the sprocket to the point
where you can see between the chain side plates and the
sprocket, the sprocket and chain are worn out, and both
must be replaced.
DANGER
Keep your fingers and clothing well clear of the chain
while you are adjusting it. Should you happen to get
any body part pinched between the chain and the
sprocket while you are turning the rear wheel, that
body part will be severely mangled. Pay particular
attention to keep your fingers clear. You will easily
lose a finger, should you pinch it between the chain
and the sprocket. We recommend wearing heavy
leather gloves when carrying out these operations,
however, be aware that even heavy leather gloves will
not protect your fingers from being mangled, should
they be caught between the chain and the sprocket.
WARNING
If the chain rollers are damaged, the pins loose and/
or the O-rings damaged or missing, you must replace
the entire assembly (both sprockets and chain),
see 7.4.1 (REMOVING
ASSEMBLY).
