The Motorcycle
Warning
Bonneville Bobber
This motorcycle is designed for use
as a two-wheeled vehicle capable of
carrying a rider on his/her own.
Operation of this motorcycle with a
passenger is dangerous and could lead
to loss of control and an accident.
The total weight of the rider,
accessories and luggage must not
exceed the maximum load limit stated
in the Specifications section.
Warning
Bonneville Speedmaster
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, passenger handhold
and footrests being fitted).
The total weight of the rider,
accessories and luggage must not
exceed the maximum load limit stated
in the Specifications section.
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.

Fuel and 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 the engine or run the
engine in a confined area.
Exhaust fumes are poisonous and can
cause loss of consciousness and death
within a short period of time.
Always operate the motorcycle in the
open air or in an area with adequate
ventilation.
Helmet and Clothing
Warning
When riding the motorcycle, both
rider and passenger (on models where
carrying a passenger is permitted)
must always wear appropriate clothing
including a motorcycle helmet, eye
protection, gloves, boots, trousers
(close fitting around the knee and
ankle) and a brightly coloured jacket.
During off-road use (on models
suitable for off-road use), the rider
must always wear appropriate clothing
including trousers and boots.
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.

Safety First
9
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
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.
Parking
Warning
Always switch 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:
- 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.

Parts and 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.
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.
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.
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.
Maintenance and 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
compromise safety.
Warning
Make sure all equipment that is
required by law is installed and
functioning correctly.
The removal or alteration of the
motorcycle’s 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, collision or fall, it must be
taken to an authorised 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.

Safety First
11
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 licenced to operate
the motorcycle.
Operation of the motorcycle without
a licence is illegal and could lead to
prosecution.
Operation of the motorcycle without
formal training in the correct riding
techniques that are necessary to
become licenced 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.

Safety First
12
Handlebars and Footrests
Warning
The rider must maintain control of the
motorcycle by keeping hands on the
handlebars at all times.
The handling and stability of a
motorcycle will be adversely affected
if the rider removes their hands from
the handlebars, resulting in loss of
motorcycle control and an accident.
Warning
The rider (and Bonneville Speedmaster
passenger) must always use the
footrests provided, during operation of
the vehicle.
By using the footrests, the rider will
reduce the risk of inadvertent contact
with any motorcycle components and
will also reduce the risk of injury from
entrapment of clothing.
Warning
Use of a motorcycle with bank angle
indicators worn beyond the maximum
limit will allow the motorcycle to be
banked to an unsafe angle. Therefore,
always replace the bank angle
indicators before they are worn to
their maximum limit.
Banking to an unsafe angle may cause
instability, loss of motorcycle control
and an accident.
Details of the bank angle wear limits
can be found in the Maintenance and
Adjustment section.
Warning
The bank angle indicators must not
be used as a guide to how far the
motorcycle may be safely banked.
This depends on many various
conditions including, but not limited
to, road surface, tyre condition
and weather. Banking to an unsafe
angle may cause instability, loss of
motorcycle control and an accident.
Warning
When banking and the bank angle
indicator, attached to the rider's
footrest, makes contact with the
ground, the motorcycle is nearing its
bank angle limit.
A further increase of the banking
angle is unsafe.
Banking to an unsafe angle may cause
instability, loss of motorcycle control
and an accident.
