Maintenance and Adjustment
Front Suspension
Front Fork Inspection
• Examine each fork stanchion 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.
Note:
• If roughness or excessive stiffness
is detected, consult your
authorised Triumph dealer.
Suspension Setting
The America and Speedmaster models both
have non-adjustable front suspension.
Rear Suspension Adjustment
1. Rear suspension pre-load adjusters -
all models
The standard rear suspension pre-load
settings provide a comfortable ride and good
handling characteristics for general, solo
riding. The table (on the facing page) shows
suggested settings for rear suspension
pre-load under differing load conditions.
To change the rear suspension spring
pre-load setting, insert a suitable tool into the
hole provided in the adjuster ring.
Turn the adjuster ring clockwise to increase
spring pre-load, and anti-clockwise to
decrease spring pre-load.
Warning
Riding the motorcycle with defective or
damaged suspension can damage the
motorcycle, cause loss of motorcycle
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.
Warning
Ensure that the adjusters are set to the
same setting on both rear suspension
units. Settings which vary from left to right
may affect handling and stability resulting
in loss of motorcycle control, and an
accident.
