To inspect the forks:
• 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.
• 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.
Rear Suspension
Caution
The rear suspension units on the
Thruxton RS are fitted 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
authorised 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.
