Warning
This motorcycle must not be operated
above the legal road speed limit except in
authorized 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 tires is
hazardous and will adversely affect
traction, stability and handling which may
lead to loss of control and an accident.
When tubeless tires become punctured,
leakage is often very slow. Always inspect
tires very closely for punctures. Check the
tires for cuts, embedded nails or other
sharp objects. Operation with punctured or
damaged tires 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 tires is dangerous and loss of
motorcycle control or an accident could
result.
Always consult your authorized Triumph
dealer for tire replacement, or for a safety
inspection of the tires.
