FOREWORD - SAFETY FIRST
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/her 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
440 lbs (200 kg).

Foreword - Safety First
Fuel and Exhaust Fumes
Warning
GASOLINE 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 gasoline on the
engine, exhaust pipes or mufflers when
refuelling.
If gasoline 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 gasoline
should immediately be removed.
Burns and other serious skin conditions
may result from contact with gasoline.
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.

Foreword - Safety First
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 the
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 license is illegal and could lead to
prosecution.
Operation of the motorcycle without
formal training in the correct riding
techniques that are necessary to become
licensed 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:
• Wind draft from passing vehicles;
• Potholes, uneven or damaged road
surfaces;
• Bad weather;
• Rider 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.

Foreword - Safety First
NOTE
Wobble/Weave
A weave is a relatively slow oscillation of the
rear of the motorcycle, while a wobble is a
rapid, possibly strong shaking of the
handlebar. These are related but distinct
stability problems usually caused by excessive
weight in the wrong place, or by a
mechanical problem such as worn or loose
bearings or under-inflated or unevenly worn
tires.
Your solution to both situations is the same.
Keep a firm hold on the handlebars without
locking arms or fighting the steering.
Smoothly ease off the throttle to slow
gradually. Do not apply the brakes, and do
not accelerate to try to stop the wobble or
weave. In some cases, it helps to shift your
body weight forward by leaning over the
tank.

Helmet and Clothing
Warning
Ensure that you know and respect the rules
of the road. Read and observe publications
such as 'MOTORCYCLE SAFETY', 'YOU
AND YOUR MOTORCYCLE, RIDING
TIPS' and also read and become familiar
with the contents of the MOTORCYCLE
HANDBOOK for your state.
Caution
This Triumph motorcycle is not fitted with
spark arresters. Operation in forests, brush
or grass areas may violate state and local
laws and regulations.
Warning
When riding the motorcycle, both rider
and passenger must always wear a
motorcycle helmet, eye protection, gloves,
trousers (close fitting around the knee and
ankle) and a brightly colored jacket.
Brightly colored 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.

9
Foreword - Safety First
When choosing a helmet, always look for a
DOT (Department of Transport) sticker
indicating that the helmet has DOT approval.
Do not buy a helmet without DOT approval.
Handlebars and Footrests
Warning
A helmet is one of the most important
pieces of riding gear as it offers protection
against head injuries. You and your
passenger's helmet should be carefully
chosen and should fit you or your
passenger's head comfortably and
securely. A brightly colored 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.
cbma
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
the 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.

Foreword - Safety First
Parking Parts and Accessories
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.
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 unauthorized
or untrained persons is reduced.
When parking the motorcycle, always
remember the following:
Engage first gear to help prevent the
motorcycle from rolling off the stand.
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.
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 authorized dealer.
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 that may result
in an accident causing injury or death.

11
Foreword - Safety First
Maintenance/Equipment
Warning
Consult your authorized 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
compromise safety.
Warning
Use of a motorcycle with bank angle
indicators worn beyond the maximum
limit (when 0.40 in (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 that is required by
law is installed and functioning correctly.
The removal or alteration of the
motorcycle’s lights, mufflers, 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,
collision or fall, it must be taken to an
authorized Triumph dealer for inspection
and repair. Any accident can cause
damage to the motorcycle that, if not
correctly repaired, may cause a second
accident that may result in injury or death.
