Steering Inspection
Warning
Riding the motorcycle with incorrectly
adjusted or defective steering
(headstock) bearings is dangerous and
may cause loss of motorcycle control
and an accident.
The steering (headstock) bearings
must be lubricated and inspected
in accordance with scheduled
maintenance requirements. Always
inspect the wheel bearings at the same
time as the steering bearings.
Inspecting the Steering for Free Play
To inspect the steering:
• Position the motorcycle on level
ground, in an upright position.
• Raise the front wheel above the
ground and support the motorcycle.
• Standing at the front of the
motorcycle, hold the lower end of
the front forks and try to move
them forward and backward.
• If any free play can be detected in
the steering (headstock) bearings,
ask your authorised Triumph dealer
to inspect and rectify any faults
before riding.
• Remove the support and place the
motorcycle on the side stand.
Wheel Bearings Inspection
Warning
Riding with worn or damaged front
or rear wheel bearings is dangerous
and may cause impaired handling and
instability leading to an accident.
If in doubt, have the motorcycle
inspected by an authorised Triumph
dealer before riding.
The wheel bearings must be inspected
at the intervals specified in the
scheduled maintenance chart.
