inspect the sprockets for unevenly or

Sprocket Wear Is Shown Exaggerated
• If there is any irregularity, have the
drive chain and sprockets replaced
by an authorized Triumph dealer.
• Install the chain guard and sprocket
cover.
Warning
The use of non-approved chains may result
in a broken chain or may cause the chain
to jump off the sprockets. Either condition
could lock the rear wheel, severely
damaging the motorcycle and causing loss
of control and an accident.
For safety, use a genuine Triumph supplied
chain as specified in the Triumph parts
catalog.
Never neglect chain maintenance and
always have chains installed by an
authorized Triumph dealer.

If the sprockets are found to be worn,
always replace the sprockets and drive
chain together.
Replacing worn sprockets without also
replacing the chain will lead to premature
wear of the new sprockets.
