your motorcycle, should be considered
a permanent part of your motorcycle
and should remain with it even if your

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 and footrests being
fitted).
The total weight of the rider, and any
passenger, accessories and luggage
must not exceed the maximum load
limit of 210 kg (463 lb).
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 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.

Safety First

Helmet and Clothing
Warning
When riding the motorcycle, both rider
and passenger must always wear a
motorcycle helmet, eye protection,
gloves, boots, 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 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.
cbma
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:
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.
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
compromise safety.
Warning
Ensure 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.

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

Handlebars and 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 their hands from the
handlebars, resulting in loss of
motorcycle control and an accident.
Warning
The rider and passenger (if applicable)
must always use the footrests
provided, 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.
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
indicator pegs 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 on page 117.
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.
