training and skills to ensure safe, effective
fitment.
Warning
On models fitted with ABS, the ABS
computer operates by comparing the
relative speed of the front and rear wheels.
Use of non-recommended tyres can affect
wheel speed and cause the ABS function
not to operate, potentially leading to loss of
control and an accident in conditions
where the ABS would normally function.
Warning
If a tyre sustains a puncture, the tyre must
be replaced. Failure to replace a
punctured tyre, or operation with a
repaired tyre can lead to instability, loss of
control or an accident.
Warning
Do not install tube-type tyres on tubeless
rims. The bead will not seat and the tyres
could slip on the rims, causing rapid tyre
deflation that may result in a loss of vehicle
control and an accident. Never install an
inner tube inside a tubeless tyre. This will
cause friction inside the tyre and the
resulting heat build-up may cause the tube
to burst resulting in rapid tyre deflation,
loss of vehicle control and an accident.

Warning
If tyre damage is suspected, such as after
striking the kerb, ask your authorised
Triumph dealer to inspect the tyre both
internally and externally. Remember, tyre
damage may not always be visible from
the outside. Operation of the motorcycle
with damaged tyres could lead to loss of
control and an accident.
