1. Measure across 20 links
2. Weight
Remove the chain guard.
Stretch the chain taut by hanging a 10 -
20 kg (20 - 40 lb) weight on the chain.
Measure the length of 20 links on the
straight part of the chain from pin
centre of the 1st pin to the pin centre of
the 21st pin. Since the chain may wear
unevenly, take measurements in several
places.
If the length exceeds the maximum
service limit of 319 mm, the chain must
be replaced.
Rotate the rear wheel and inspect the
drive chain for damaged rollers, and
loose pins and links.
Also inspect the sprockets for unevenly
or excessively worn or damaged teeth.

If there is any irregularity, have the
drive chain and/or
replaced by an authorised Triumph
dealer.
Refit the chain guard, tightening the
fixings to 9 Nm.
Warning
Never neglect chain maintenance and
always have chains installed by an
authorised Triumph dealer.
Use a genuine Triumph-supplied chain
as specified in the Triumph Parts
Catalogue.
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.
