Maintenance and Adjustment
Tyre Replacement
All Triumph motorcycles are carefully and
extensively tested in a range of riding
conditions to ensure that the most effective
tyre combinations are approved for use on
each model. It is essential that approved tyres,
fitted in approved combinations, are used
when purchasing replacement tyres. The use
of non-approved tyres, or approved tyres in
non-approved combinations, may lead to
motorcycle instability and an accident. On
models fitted with ABS, different wheel
speeds, caused by fitting non-approved tyres
can affect the function of the ABS computer.
See the Specification section for details of
approved tyre combinations. Always have
tyres fitted and balanced by your authorised
Triumph dealer who has the necessary
training and skills to ensure safe, effective
fitment.
Warning
Only operate this Triumph motorcycle at
high speed in closed-course on-road
competition or on closed-course racetracks.
High-speed operation should only then be
attempted by riders who have been
instructed in the techniques necessary for
high-speed riding and are familiar with the
motorcycle's characteristics in all
conditions. High-speed operation in any
other circumstances is dangerous and will
lead to loss of motorcycle control and an
accident.
Warning
Operation with excessively worn tyres is
hazardous and will adversely affect
traction, stability and handling which may
lead to loss of control and an accident.
When tubeless tyres become punctured,
leakage is often very slow. Always inspect
tyres very closely for punctures. Check the
tyres for cuts, embedded nails or other
sharp objects. Operation with punctured or
damaged tyres will adversely affect
motorcycle stability and handling which
may lead to loss of control or an accident.
Check the rims for dents or deformation.
Operation with damaged or defective
wheels or tyres is dangerous and loss of
motorcycle control or an accident could
result.
Always consult your authorised Triumph
dealer for tyre replacement, or for a safety
inspection of the tyres.
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.
