If there is any irregularity, have the
drive chain and/or the sprockets
replaced by an authorized Triumph
dealer.
Re-install the chain guard, tightening
the fasteners to

Nm
.
Warning
Never neglect chain maintenance and
always have chains installed by an
authorized Triumph dealer. Use a
genuine Triumph supplied chain as
specified in the Triumph Parts Catalog.
The use of non-approved chains may
result in a broken chain or may cause
the chain to jump off the sprockets
leading to loss of motorcycle control or
an accident.
Caution
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.
