Maintenance and Adjustment
Turn the adjuster ring clockwise to increase
spring pre-load, and anti-clockwise to
decrease spring pre-load. When delivered
from the factory, the pre-load adjuster will be
set at position 1.
Suggested Suspension Settings
Adjuster settings are counted from position
one with position one being with the adjuster
turned fully counter-clockwise. There are five
positions in total. Position 1 gives the
minimum amount of spring pre-load.
Note:
• The details given in the table are
only a guide. Setting requirements
may vary for rider and passenger
weight and personal preferences.
For Thunderbird Horizon only: Refit the
panniers (see page 50 ).
Final Drive Belt
For safety and to prevent excessive wear the
drive belt must be checked, adjusted and
renewed in accordance with scheduled
maintenance requirements. Checking and
adjustment must be carried out more
frequently for extreme conditions such as
salty or heavily gritted roads.
If the drive belt is badly worn or incorrectly
adjusted (either too loose or too tight) the
belt could jump off the drive belt pulleys or
break. Therefore, always replace worn or
damaged drive belts using genuine Triumph
parts supplied by an authorized Triumph
dealer. The drive belt requires no lubrication.
Warning
Ensure that the adjusters are set to the
same setting on both rear suspension
units. Settings that vary from left to right
may affect handling and stability resulting
in loss of motorcycle control and an
accident.
