Maintenance and Adjustment
Tyre Wear
As the tyre tread wears down, the tyre
becomes more susceptible to punctures. It is
estimated that 90% of all tyre problems occur
during the last 10% of tread life (90% worn).
It is therefore not recommended to use tyres
until they are worn to their minimum.
Minimum Recommended
Tread Depth
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 130 km/h
(80 mph)
2 mm (0.08 in)
Over 130 km/h
(80 mph)
Rear 3 mm (0.12 in)
Front 2 mm (0.08 in)
Warning
This motorcycle must not be operated
above the legal road speed limit except in
authorised closed-course conditions.
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 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 stability
and handling which may lead to loss of
control or an accident.
Check the rims for dents or deformation
and spokes for looseness and damage.
Operation with damaged or defective
wheels, spokes or tyres is dangerous and
loss of control or an accident could result.
Always consult your authorised Triumph
dealer for tyre replacement, or for a safety
inspection of the wheels, spokes and tyres.
