Inspecting the Steering (Headstock)
Bearings for Free Play
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
If the wheel bearings in the front or rear
wheel allow play in the wheel hub, are noisy,
or if the wheel does not turn smoothly, have
your authorised Triumph dealer inspect the
wheel bearings.
The wheel bearings must be inspected at the
intervals specified in the scheduled
maintenance chart.
Position the motorcycle on level ground, in an
upright position.
Raise the front wheel above the ground and
support the motorcycle.
Standing at the side of the motorcycle, gently
rock the top of the front wheel from side to
side.
If any free play can be detected, ask your
authorised Triumph dealer to inspect and
rectify any faults before riding.
Reposition the lifting device and repeat the
procedure for the rear wheel.
Warning
Riding the motorcycle with incorrectly
adjusted or defective steering (headstock)
bearings is dangerous and may cause loss
of motorcycle control and an accident.
