Fork Inspection
Warning
Riding the motorcycle with defective or
damaged suspension is dangerous and
may lead to loss of control and an
accident.
Warning
Never attempt to dismantle any part of
the suspension units, as all units
contain pressurised oil. Skin and eye
damage can result from contact with
the pressurised oil.
Examine each fork for any sign of
damage, scratching of the slider
surface, or for oil leaks.
If any damage or leakage is found,
consult an authorised Triumph dealer.
To check that the forks operate smoothly:
• Position the motorcycle on level
ground.
• While holding the handlebars and
applying the front brake, pump the
forks up and down several times.
• If roughness or excessive stiffness
is detected, consult your authorised
Triumph dealer.
