Maintenance and Adjustment
Chain and Sprocket Wear Inspection
1. Measure across 20 links
2. Weight
Remove the chain guards.
Stretch the chain taut by hanging a
20 - 40 lb (10 - 20 kg) weight on the chain.
Measure the length of 20 links on the
straight part of the chain from pin center of
the 1
st
pin to the pin center of the 21
st
pin.
Since the chain may wear unevenly, take
measurements in several places.
If the length exceeds the maximum service
limit of 12.63 in (321 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 the sprockets replaced by an
authorized Triumph dealer.
Re-install the chain guards.
Warning
It is dangerous to operate the motorcycle
with defective brakes; you must have your
authorized Triumph dealer take remedial
action before you attempt to ride the
motorcycle again. Failure to take remedial
action may reduce braking efficiency
leading to loss of control or an accident.

Warning
The use of non-approved chains may result
in a broken chain or may cause the chain
to jump off the sprockets.
Use a genuine Triumph supplied chain as
specified in the Triumph parts catalogue.
Never neglect chain maintenance and
always have chains installed by an
authorized Triumph dealer.
