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, used without a
tube, 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.
In accordance with the periodic
maintenance chart, measure the depth
of the tread with a depth gauge, and
replace any tyre that has worn to, or
beyond the minimum allowable tread
depth specified in the table below:
Under 80 mph
(130 km/h)
2 mm (0.08 in)
Over 80 mph
(130 km/h)
Front 2 mm (0.08 in)
Rear 3 mm (0.12 in)
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 and inner
tubes (if installed) fitted in approved
combinations, are used when
purchasing replacement items. The use
of non-approved tyres and inner tubes,
or approved tyres and inner tubes in
non-approved combinations, may lead
to motorcycle instability, loss of control
and an accident.
A list of approved tyres and inner tubes
specific to your motorcycle are available
from your authorised Triumph dealer, or
on the Internet at www.triumph.co.uk.
Always have tyres and inner tubes
fitted and balanced by your authorised
Triumph dealer who has the necessary
training and skills to ensure safe,
effective fitment.
Different wheel speeds, caused by non-
approved tyres, can affect the function
of the ABS computer.
Warning
The ABS system 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.
