Rear Suspension
Caution
The rear suspension units on the
Thruxton RS are equipped with a
protective film label. This protective
film label will gradually wear. This wear
is normal and not considered to be a
fault. It does not affect the safety,
operation or performance of the rear
suspension.
If the motorcycle is used in dirty
or dusty environments, the wear
on the protective film labels will be
accelerated.
To reduce the wear on the protective
film labels, dirt should be washed from
between them after use in dirty or
dusty environments.
The protective film labels are
replaceable and can be replaced by an
authorized Triumph dealer.
The Thruxton RS suspension has three
different rear adjustment settings;
spring preload, rebound damping and
compression damping. All other models
only have adjustable spring preload
settings.
The Standard rear suspension preload
settings provide a comfortable ride
and good handling characteristics
for general, solo riding. The following
tables show suggested settings for
rear suspension under different load
conditions for all models.

The details shown in the tables are only
a guide. Setting requirements may vary
for rider and passenger weight and
personal preferences.
