SAFETY INFORMATION
EAU10251
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 BEFORE RIDING THIS
MOTORCYCLE.
HE OR SHE SHOULD:
● OBTAIN THOROUGH INSTRUC-
TIONS FROM A COMPETENT
SOURCE ON ALL ASPECTS OF
MOTORCYCLE OPERATION.
● OBSERVE THE WARNINGS
AND MAINTENANCE REQUIREMENTS IN THE OWNER’S MANUAL.
● OBTAIN QUALIFIED TRAINING
IN SAFE AND PROPER RIDING
TECHNIQUES.
● OBTAIN PROFESSIONAL TECH-
NICAL SERVICE AS INDICATED
BY THE OWNER’S MANUAL
AND/OR WHEN MADE NECESSARY BY MECHANICAL CONDITIONS.
Safe riding
● Always make pre-operation
checks. Careful checks may help
prevent an accident.
● This motorcycle is designed to
carry the operator and a passenger.
● 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 motorcycle.
Making yourself conspicuous appears to be very effective in reducing the chance of this type of
accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when ap-
proaching and passing through
intersections, since intersec-
1-1
tions are the most likely places
for motorcycle accidents to occur.
• Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.
● Many motorcycle accidents in-
volve inexperienced operators. In
fact, many operators who have
been involved in accidents do not
even have a current motorcycle license.
• Make sure that you are qualified
and that you only lend your
motorcycle to other qualified operators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you practice riding your motorcycle
where there is no traffic until you
have become thoroughly familiar with the motorcycle and all of
its controls.
● Many motorcycle accidents have
been caused by error of the motorcycle operator. A typical error
made by the operator is veering
1
SAFETY INFORMATION
wide on a turn due to EXCESSIVE
SPEED or undercornering (insufficient lean angle for the speed).
1
• Always obey the speed limit and
never travel faster than warranted by road and traffic conditions.
• Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
● The posture of the operator and
passenger is important for proper
control.
• The operator should keep both
hands on the handlebar and
both feet on the operator footrests during operation to maintain control of the motorcycle.
• The passenger should always
hold onto the operator, seat
strap, or grab bar, if equipped,
with both hands and keep both
feet on the passenger footrests.
• Never carry a passenger unless
he or she can firmly place both
feet on the passenger footrests.
● Never ride under the influence of
alcohol or other drugs.
● This motorcycle is designed for on-
road use only, therefore, it is not
suitable for off-road use.
Protective apparel
The majority of fatalities from motorcycle accidents are the result of head
injuries. The use of a safety helmet is
the single most critical factor in the prevention or reduction of head injuries.
● Always wear an approved helmet.
● Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment
of vision which could delay seeing
a hazard.
● The use of a jacket, heavy boots,
trousers, gloves, etc., is effective in
preventing or reducing abrasions
or lacerations.
● Never wear loose-fitting clothes,
otherwise they could catch on the
control levers, footrests, or wheels
and cause injury or an accident.
● Never touch the engine or exhaust
system during or after operation.
They become very hot and can
cause burns. Always wear protective clothing that covers your legs,
ankles, and feet.
● Passengers should also observe
the precautions mentioned above.
Modifications
Modifications made to this motorcycle
not approved by Yamaha, or the removal of original equipment, may render the 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 motorcycle is changed. To avoid
the possibility of an accident, use extreme caution when adding cargo or
accessories to your motorcycle. Use
extra care when riding a motorcycle
that has added cargo or accessories.
Here are some general guidelines to
follow if loading cargo or adding accessories to your motorcycle:
1-2
SAFETY INFORMATION
Loading
The total weight of the operator, passenger, accessories and cargo must
not exceed the maximum load limit.
Maximum load:
XVS650 178 kg (392 lb) (CAL)
XVS650 180 kg (397 lb) (U49)
XVS650A 198 kg (437 lb) (CAL)
XVS650A 200 kg (441 lb) (U49)
XVS650AT 198 kg (437 lb) (CAL)
XVS650AT 200 kg (441 lb) (U49)
When loading within this weight limit,
keep the following in mind:
● Cargo and accessory weight
should be kept as low and close to
the motorcycle as possible. Make
sure to distribute the weight as
evenly as possible on both sides of
the motorcycle to minimize imbalance or instability.
● Shifting weights can create a sud-
den imbalance. Make sure that accessories and cargo are securely
attached to the motorcycle before
riding. Check accessory mounts
and cargo restraints frequently.
● Never attach any large or heavy
items to the handlebar, front fork,
or front fender. These items, including such cargo as sleeping
bags, duffel 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 that may be
available, you must personally be responsible for the proper selection, installation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any accessories.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.
● Never install accessories or carry
cargo that would impair the perfor-
mance of your motorcycle. Care-
fully inspect the accessory before
using it to make sure that 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.
• Accessories fitted to the handlebar or the front fork area can
create instability due to improper
weight distribution or aerodynamic changes. If accessories
are added to the handlebar or
front fork area, they must be as
lightweight as possible and
should be kept to a minimum.
• Bulky or large accessories may
seriously affect the stability of
the motorcycle due to aerodynamic effects. Wind may attempt to lift the motorcycle, or
the motorcycle may become unstable in cross winds. These accessories may also cause
instability when passing or being
passed by large vehicles.
• Certain accessories can displace the operator from his or
her normal riding position. This
improper position limits the freedom of movement of the opera-
1
1-3
SAFETY INFORMATION
tor and may limit control ability,
therefore, such accessories are
not recommended.
1
● Use caution when adding electri-
cal accessories. If electrical accessories exceed the capacity of the
motorcycle’s electrical system, an
electric failure could result, which
could cause a dangerous loss of
lights or engine power.
Gasoline and exhaust gas
● GASOLINE IS HIGHLY FLAMMA-
BLE:
• Always turn the engine off when
refueling.
• Take care not to spill any gasoline on the engine or exhaust
system when refueling.
• Never refuel while smoking or in
the vicinity of an open flame.
● 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
motorcycle in an area that has adequate ventilation.
● Always turn the engine off before
leaving the motorcycle unattended
and remove the key from the main
switch. When parking the motorcycle, note the following:
• The engine and exhaust system
may be hot, therefore, park the
motorcycle in a place where pedestrians or children are not likely to touch these hot areas.
• Do not park the motorcycle on a
slope or soft ground, otherwise it
may fall over.
• Do not park the motorcycle near
a flammable source (e.g. a kerosene heater, or near an open
flame), otherwise it could catch
fire.
● When transporting the motorcycle
in another vehicle, make sure that
it is kept upright and that the fuel
cock is turned to “ON” or “RES” (for
vacuum type) / “OFF” (for manual
type). If it should lean over, gasoline may leak out of the carburetor
or fuel tank.
● If you should swallow any gaso-
line, inhale a lot of gasoline vapor,
or allow gasoline to get into your
1-4
eyes, see your doctor immediately.
If any gasoline spills on your skin
or clothing, immediately wash the
affected area with soap and water
and change your clothes.
