safety and performance. Please read this owner’s handbook before riding in order to become
thoroughly familiar with the correct operation of your motorcycle’s controls, its features,
capabilities and limitations.
This owner’s handbook includes safe riding tips, but does not contain all the techniques and
skills necessary to ride a motorcycle safely. Triumph strongly recommends that all riders

All riders must read this owner’s handbook and all other instructions which are
supplied with your motorcycle before riding in order to become thoroughly familiar
with the correct operation of your motorcycle’s controls, its features, capabilities
and limitations. Do not lend your motorcycle to others, as riding when not familiar

THE MOTORCYCLE
WARNING: This motorcycle
is designed for on-road use
only. It is not suitable for off-road use.
Off-road operation could lead to loss
of control of the motorcycle resulting
in an accident causing injury or loss
of life.
WARNING: This motorcycle
is not designed to tow a trailer
or be fitted with a sidecar. Fitting a
sidecar and/or a trailer may result in
loss of control and an accident.
WARNING: This motorcycle
is designed for use as a
two--wheeled vehicle capable of
carrying a rider on his own, or a rider
and one passenger (subject to a
passenger seat being fitted).
The total weight of the rider, and any
passenger, accessories and luggage
must not exceed the maximum load
limit of 200 kg (440 lbs).
FUEL & EXHAUST FUMES
WARNING: PETROL IS
HIGHLY FLAMMABLE:
Always turn off the engine when
refuelling.
Do not refuel or open the fuel filler cap
while smoking or in the vicinity of any
open (naked) flame.
Take care not to spill any petrol on the
engine, exhaust pipes or silencers
when refuelling.
If petrol is swallowed, inhaled or
allowed to get into the eyes, seek
immediate medical attention.
Spillage on the skin should be
immediately washed off with soap
and water and clothing contaminated
with petrol should immediately be
removed.
Burns and other serious skin
conditions may result from contact
with petrol.
WARNING: Never start your
engine or let it run for any
length of time in a closed area. The
exhaust fumes are poisonous and
may cause loss of consciousness and
death within a short time. Always
operate your motorcycle in the
open--air or in an area with adequate
ventilation.

CRASH HELMET & CLOTHING
WARNING: When riding the
motorcycle both rider and
passenger must always wear a crash
helmet, eye protection, gloves,
trousers (close fitting around the
knee and ankle) and a brightly
coloured jacket. Brightly coloured
clothing will considerably increase a
rider’s (or passenger’s) visibility to
other operators of road vehicles.
Although full protection is not
possible, wearing correct protective
clothing can reduce the risk of injury
when riding.
WARNING: A crash helmet is
one of the most important
pieces of riding gear as it offers
protection against head injuries. You
and your passenger’s crash helmet
should be carefully chosen and
should fit you or your passenger’s
head comfortably and securely. A
brightly coloured helmet will increase
a rider’s (or passenger’s) visibility to
other operators of road vehicles.
An open face helmet offers some
protection in an accident though a full
face helmet will offer more.
Always wear a visor or approved
goggles to help vision and to protect
your eyes.
HANDLEBARS & FOOTRESTS
WARNING: The rider must
maintain control of the
vehicle by keeping hands on the
handlebars at all times.
The handling and stability of a
motorcycle will be adversely affected
if the rider removes his hands from
the handlebars, resulting in loss of
control or an accident.
WARNING: Footrests
provided must always be
used by rider and passenger during
operation of the vehicle.
By using the footrests, both rider and
passenger will reduce the risk of
inadvertent contact with any
motorcycle components and will also
reduce the risk of injury from
entrapment of clothing.

RIDING
WARNING: Never ride the
motorcycle when fatigued or
under the influence of alcohol or
other drugs.
Riding when under the influence of
alcohol or other drugs is illegal.
Riding when fatigued or under the
influence of alcohol or other drugs
reduces the rider’s ability to maintain
control of motorcycle and may lead to
loss of control and an accident.
WARNING: All riders must be
licensed to operate the
motorcycle. Operation of the
motorcycle without a licence is illegal
and could lead to prosecution. In
addition, operation without a licence
is dangerous and may lead to loss of
motorcycle control and an accident.
WARNING: Always ride
defensively and wear the
protective equipment mentioned
elsewhere in this foreword.
Remember, in an accident, a
motorcycle does not give the same
impact protection as a car.
WARNING: This Triumph
motorcycle should be
operated within the legal speed limits
for the particular road travelled.
Operating a motorcycle at high
speeds can be potentially dangerous
since the time available to react to
given traffic situations is greatly
reduced as road speed increases.
Always reduce speed in potentially
hazardous driving conditions such as
bad weather or heavy traffic.
WARNING: Continually
observe and react to changes
in road surface, traffic and wind
conditions. All two--wheeled vehicles
are subject to external forces which
may cause an accident. These forces
include but are not limited to:
SWind draft from passing vehicles.
SUneven or holed road surfaces.
SBad weather.
SRider error.
Always operate the motorcycle at
moderate speed and away from heavy
traffic until you have become
thoroughly familiar with its handling
and operating characteristics. Never
exceed the legal speed limit.

PARKING
WARNING: Always turn off
the engine and remove the
ignition key before leaving the
motorcycle unattended. By removing
the key, the risk of use of the
motorcycle by unauthorised or
untrained persons is reduced.
When parking the motorcycle, always
remember the following:--
The engine and exhaust system will
be hot after riding. DO NOT park
where pedestrians, animals and/or
children are likely to touch the
motorcycle.
Do not park on soft ground or on a
steeply inclined surface. Parking
under these conditions may cause the
motorcycle to fall over.
For further details, please refer to the
‘How to Ride the Motorcycle’ section
of this owner’s handbook.
PARTS & ACCESSORIES
WARNING: Owners should
be aware that the only
approved parts, accessories and
conversions for any Triumph
motorcycle are those which carry
official Triumph approval and are
fitted to the motorcycle by an
authorised dealer.
Triumph does not accept any liability
whatsoever for defects caused by the
fitting of non--approved parts,
accessories or conversions or the
fitting of any approved parts,
accessories or conversions by
non--approved personnel.
In particular, it is extremely
hazardous to fit or replace parts or
accessories whose fitting requires
the dismantling of, or addition to,
either the electrical or fuel systems
and any such modification could
cause a safety hazard.
The fitting of any non--approved
parts, accessories or conversions
may adversely affect the handling,
stability or other aspect of the
motorcycle operation which may
result in an accident causing injury or
death.

MAINTENANCE & EQUIPMENT
WARNING: Consult your
authorised Triumph dealer
whenever there is doubt as to the
correct or safe operation of this
Triumph motorcycle.
Remember that continued operation
of an incorrectly performing
motorcycle may aggravate a fault and
may also prejudice safety.
WARNING: Use of a
motorcycle with bank angle
indicators worn beyond the maximum
limit (when 10 mm or more of the
radiused tip of either front footrest is
worn away) will allow the motorcycle
to be banked to an unsafe angle.
Never change the setting of the brake
pedal adjustment pushrod as this
may adversely affect the bank angle at
which the bank angle indicators
contact the ground.
Banking to an unsafe angle may
cause instability, loss of control and
an accident causing injury or death.
WARNING: Ensure all
equipment which is required
by law is installed and functioning
correctly.
The removal or alteration of the
motorcycles lights, silencers,
emission or noise control systems
can violate the law.
Incorrect or improper modification
may adversely affect the handling,
stability or other aspect of the
motorcycle operation which may
result in an accident causing injury or
death.
WARNING: If the motorcycle
is involved in an accident or
collision it must be taken to an
authorised Triumph dealer for
inspection and repair. Any accident
can cause damage to the motorcycle
which, if not correctly repaired, may
cause a second accident which may
result in injury or death.
