Drive Chain

Warning
A loose or worn chain, or a chain that
breaks or jumps off the sprockets
could catch on the engine sprocket or
lock the rear wheel.
A chain that snags on the engine
sprocket will injure the rider and lead
to loss of motorcycle control and an
accident.
Similarly, locking the rear wheel will
lead to loss of motorcycle control and
an accident.
For safety and to prevent excessive
wear the drive chain must be checked,
adjusted and lubricated in accordance
with scheduled
requirements. Checking, adjustment and
lubrication must be carried out more
frequently for extreme conditions such
as salty or heavily gritted roads.
If the chain is badly worn or incorrectly
adjusted (either too loose or too tight)
the chain could jump off the sprockets
or break. Therefore, always replace worn
or damaged chains
Triumph parts supplied by an authorized
Triumph dealer.

Drive Chain Lubrication

Lubrication is necessary every 200 miles
(300 km) and also after riding in wet
weather, on wet roads, or any time that
the chain appears dry.

maintenance
using genuine
To lubricate the drive chain:
• Use the special chain lubricant as
recommended in the Specifications
section.
• Apply lubricant to the sides of the
rollers then allow the motorcycle to
stand unused for at least eight
hours (overnight is ideal). This will
allow the oil to penetrate to the
chain O-rings etc.
• Before riding, wipe off any excess
oil.
• If the chain is especially dirty, clean
first and then apply oil as mentioned
above.
Caution
Do not use a pressure washer to clean
the chain as this may cause damage
to the chain components.
