Maintenance and Adjustment
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 (overleaf) 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.
Suggested Suspension Settings
Front adjuster settings refer to the number of
exposed graduation lines. There are seven
adjuster positions in total. Position one gives
the maximum amount of spring pre-load.
Rear adjuster settings are counted from one
with position one being with the adjuster
turned fully anti-clockwise. There are five
adjuster positions in total. Position one gives
the minimum amount of spring pre-load.
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.

Warning
Ensure that the correct balance between
front and rear suspension is maintained.
Suspension imbalance could significantly
change handling characteristics leading to
loss of control and an accident. Refer to the
chart for further information or consult
your Triumph dealer.
