LI':,
TIPS FOR SAFETY
TWO-WHEELED
MOTORCYCLES
ARE
SINGLE
TRACK
VEHICLES.
THEIR
SAFE
USE
AND
OPERATION
ARE
DEPENDENT
UPON
THE
USE
OF
PROPER
RIDING
TECHNIQUES
AS
WELL
AS
THE
EXPERTISE OF
THE
OPERATOR.
EVERY
OPERATOR
SHOULD
KNOW
THE
FOLLOWING
REQUIREMENTS
BE-
FORE
RIDING.
HE OR SHE
SHOULD:
1.
OBTAIN
THOROUGH
INSTRUCTIONS
FROM
A
COMPETENT
SOURCE
ON
ALL
ASPECTS
OF
MOTORCYCLE
OPERATION.
2.
OBSERVE
THE
WARNINGS
AND
MAINTENANCE
REQUIREMENTS
IN
THE
OWNER'S
MANUAL.
3.
OBTAIN
QUALIFIED
TRAINING
IN
SAFE
AND
PROPER
RIDING
TECHNIQUES.
4.
OBTAIN

AS
INDICATED
BY

MANUAL
AND/OR

MADE
NECESSARY
BY

CONDITIONS.

______
---
SAFE
RIDING
1.
Always
make
pre-operation
checks.
Careful
checks
may
help
prevent
an
ac-
cident.
2.
This
motorcycle
is
designed
to
carry
the
operator
only
No
passengers.
3.
The
failure
of
motorists
to
detect
and
recognize
motorcycles
in
traffic
is
the
predominating
cause
of
automobile/motorcycle
accidents.
Many
accidents
have
been
caused
by
an
automobile
driver
who
did
not
see
the
mtorcycle.
Making
yourself
conspicuous
appears
to
be
very
effective
in
reducing
the
chance
of
this
type
of
accident.
Therefore:
a.
Wear a brightly
colored
jacket.
b.
Use
extra
caution
when
you
approach
and
pass
through
intersections,
since
intersections
are
the
most
likely
places
for
motorcycle
accidents.
c.
Ride
where
other
motorists
can
see
you.
Avoid
riding
in
another
motorist's
"blind
spot."
4.
Many
accidents
involve
inexperienced
operators.
In
fact,
many
operators
who
have
been
involved
in
accidents
do
not
even
have a current
motorcycle
license.
a.
Make
sure
you
are
qualified.
Also,
only
lend
your
motorcycle
to
experi-
enced
operators.
b.
Know
your
skills
and
limits.
Staying
within
your
limits
may
help
you
to
avoid
an
accident.
c.
We
recommend
that
you
practice
riding
your
motorcycle
where
there
is
no
traffic
until
you
have
become
thoroughly
familiar
with
your
motorcycle
and
all
of
its
controls.
5.
Many
motorcycle
accidents
have
been
caused
by
motorcycle
operator
errors.
A
typical
error
made
by
the
operator
is
veering
wide
on a turn
due
to
EX-
CESSIVE
SPEED
or
undercornering
(insufficient
lean
angle
for
the
speed).
a.
Always
obey
the
speed
limits
and
never
travel
faster
than
warranted
by
road
and
traffic
conditions.
b.
Always
signal
before
turning
or
changing
lanes.
Make
sure
other
motorists
see
you.
6.
Operator's
posture
is
important
for
proper
control.
The
operator
should
keep
both
hands
on
the
handlebars
and
both
feet
on
the
operator
footrests
during
operation
to
maintian
control
of
the
motorcycle.
7.
Never
ride
under
the
influence
of
alcohol
or
drugs.
PROTECTIVE
APPAREL
The
majority
of
fatalities
from
motorcycle
accidents
are
the
result
of
head
in-
juries.
The
use
of a safety
helmet
is
the
single
most
critical
factor
in
the
pre-
vention
or
reduction
of
head
injuries.
-
---
-------
-------
---
1.
Always
wear
an
approved
helmet.
2.
Wear a face
shield
or
goggles.
Wind
on
your
unprotected
eyes
could
con-
tribute
to
an
impairment
of
vision
which
could
delay
seeing a hazard.
3.
The
use
of
heavy
boots,
jacket,
trousers,
gloves,
etc.
is
effective
in
preventing
or
reducing
abrations
or
lacerations.
4.
Never
wear
loose
fitting
clothing.
It
could
catch
on
the
control
levers,
footrests,
or
wheels
and
cause
injury
or
accident.
5.
Never
touch
the
engine
or
exhaust
system
during
or
after
operation.
They
become
very
hot
and
can
cause
burns.
Always
wear
protective
clothings
that
covers
your
legs,
ankles,
and
feet.
MODIFICATION
Modifications
made
to
the
motorcycle
not
approved
by
Yamaha,
or
the
removal
of
original
equipment,
may
render
your
motorcycle
unsafe
for
use
and
may
cause
severe
personal
injury.
Modifications
may
also
make
your
motorcycle
illegal
to
use.
LOADING
AND
ACCESSORIES
Adding
accessories
or
cargo
to
your
motorcycle
can
adversely
affect
stability
and
handling
if
the
weight
distribution
of
the
machine
is
changed.
To
avoid
the
possibility
of
an
accident,
extreme
caution
should
be
used
if
adding
cargo
or
accessories
to
your
motorcycle.
Use
extra
care
if
riding a motorcycle
which
has
added
cargo
or
accessories.
Here
are
some
general
guidelines
to
follow
if
loading
cargo
or
adding
accessories
to
your
motorcycle:
LOADING
The
total
weight
of
the
operator,
accessories
and
cargo
must
not
exceed
the
maximum
load
limit
of
157
lbs.
(71
kg).
When
loading
within
these
weight
limits,
keep
the
following
in
mind:
1.
Cargo
and
accessory
weight
should
be
kept
as
low
and
close
to
the
motorcycle
as
possible.
Be
sure
to
distribute
the
weight
as
evenly
as
possible
on
both
sides
of
the
machine
to
minimize
imbalance
or
instability.
2.
Shifting
weights
can
create a sudden
imbalance.
Make
sure
that
accessories
and
cargo
are
securely
attached
to
the
motorcycle
before
riding.
Recheck
accessory
mounts
and
cargo
restraints
frequently.
3.
Never
attach
any
large
or
heavy
items
to
the
handlebars,
front
forks,
or
front
fender.
These
items,
including
such
cargo
as
sleeping
bags,
duffle
bags,
or
tents,
can
create
unstable
handling
or
slow
steering
response.
ACCESSORIES
Genuine
Yamaha
accessories
have
been
specifically
designed
for
use
on
this
motorcycle.
Since
Yamaha
cannot
test
all
other
accessories
which
may
be
available,
you
must
personally
be
responsible
for
the
proper
selection,
instal-
lation
and
use
of
non-Yamaha
accessories.
You
should
use
extreme
caution
when
selecting
and
installing
any
accessories.
Keep
in
mind
these
guidelines
for
mounting
accessories
in
addition
to
those
provided
under
"LOADING''.
1.
Never
install
accessories
or
carry
cargo
that
would
impair
the
performance
of
your
motorcycle.
Carefully
inspect
the
accessory
before
using
it
to
make
sure
it
does
not
in
any
way
reduce
ground
clearance
or
cornering
clearance,
limit
suspension
travel,
steering
travel
or
control
operation,
or
obscure
lights
or
reflectors.
a.
Accessories
fitted
to
the
handlebar
or
the
front
fork
area
can
create
in-
stability
due
to
improper
weight
distribution
or
aerodynamic
changes.
If
accessories
are
added
to
the
handlebar
or
front
fork
area,
they
must
be
as
light
weight
as
possible
and
should
be
kept
to a minimum.
b.
Bulky
or
large
accessories
may
seriously
affect
the
stability
of
the
mo-
torcycle
due
to
aerodynamic
effects.
Wind
may
attempt
to
lift
the
mo-
torcycle,
or
the
motorcycle
may
become
unstable
in
cross
winds.
These
accessories
may
also
cause
instability
when
being
passed
by
or
passing
large
vehicle.
c.
Certain
accessories
can
displace
the
operator
from
his
or
her
normal
riding
position.
This
improper
position
limits
the
freedom
of
movement
of
the
operator
and
may
limit
control
ability.
Therefore
such
accessories
are
not
recommended.
2.
Caution
must
be
used
if
adding
electrical
accessories.
If
these
accessories
exceed
the
capacity
of
motorcycle's
electrical
system,
an
electric
failure
could
result,
which
could
cause a dangerous
loss
of
lights
or
engine
power.
GASOLINE
AND
EXHAUST GAS
1. GASOLINE IS HIGHLY
FLAMMABLE:
a.
Always
turn
off
the
engine
when
refueling.
b.
Take
care
not
to
spill
any
gasoline
on
the
engine
or
exhaust
pipe(s)/muffler(s)
when
refueling.
c.
Never
refuel
while
smoking
or
in
the
vicinity
of
an
open
flame.
2.
Never
start
the
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
motorycle
in
an
area
that
has
adequate
ventilation.
3.
Always
turn
off
the
engine
before
leaving
the
motorcycle
unattended
and
remove
the
ignition
key.
When
parking
the
motorcycle,
note
the
following:
a.
The
engine
and
exhaust
pipe(s)/muffler(s)
may
be
hot.
Park
the
motorcycle
in a place
where
pedestrians
or
children
are
not
likely
to
touch
these
hot
areas.
b.
Do
not
park
the
motorcycle
on a slope
or
soft
ground:
the
motorcycle
may
fall
over.
c.
Do
not
park
the
motorcycle
near
an
flammable
source,
e.g. a kerosene
heater,
or
near
an
open
flame.
The
motorcycle
could
catch
fire.
4.
When
transporting
the
motorcycle
in
another
vehicle,
be
sure
it
is
kept
upright
and
that
the
fuel
cock(s)
is
turned
to
"ON"
or
"RES"
(for
vacuum
type)/"OFF"
(for
manual
type).
If
it
should
lean
over,
gasoline
may
leak
out
of
the
car-
buretor
or
fuel
tank.
5.
If
you
should
swallow
any
gasoline,
inhale a lot
of
gasoline
vapor,
or
allow
gasoline
to
get
in
your
eye(s),
see
your
doctor
immediately.
If
any
gasoline
spills
on
your
skin
or
clothing,
immediately
wash
with
soap
and
water
and
change
your
clothes.
