SAFETY INFORMATION
EAU00014
TWO-WHEELED MOTORCYCLES ARE SINGLE TRACK VEHICLES. THEIR SAFE USE AND
OPERATION ARE DEPENDENT UPON THE USE OF PROPER RIDING TECH NIQUES AS WELL
AS THE EXPERTISE OF THE OPERATOR.
1
EVERY OPERATOR SHOULD KNOW THE FOLLOWING REQUIREMENTS BEFORE 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 PROFESSIONAL TECHNICAL SERVICE AS INDICATED BY THE OWNER’S MANUAL
AND/OR WHEN MADE NECESSARY BY MECHANICAL CONDITIONS.
Safe riding
1. Always make pre-operation checks. Careful checks may help prevent an accident.
2. This motorcycle is designed to carry the operator and a passenger.
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 motorcycle. 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”.
1-1
SAFETY INFORMATION
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 experienced 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 EXCESSIVE 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 condi-
tions.
b. Always signal before turning or changing lanes. Make sure other motorists see you.
6. The operator’s and passenger’s posture are important for proper control.
a. The operator should keep both hands on the handlebars and both feet on the operator footrests
during operation to maintain control of the motorcycle.
b. The passenger should always hold on to the operator, or the seat strap or grab bar if the motor-
cycle is so equipped, with both hands and keep both feet on the passenger footrests.
c. Never carry a passenger unless he or she can firmly place both feet on the passenger footrests.
7. Never ride under the influence of alcohol or drugs.
8. This motorcycle is designed for on-road use only. It is not suitable for off-r oad use.

SAFETY INFORMATION
Protective apparel
The majority of fatalities from motorcycle accid en ts are the resu lt of he ad injuri es. Th e u se of a saf et y
1
helmet is the single most critical factor in the prevention or reduction of head injuries.
1. Always wear an approved helmet.
2. Wear a face shield or goggles. Wind on your unprotected eyes could contribute 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 abrasions
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 ca n
cause burns. Always wear protective clothing that covers your legs, ankles, and feet.
6. A passenger should also observe the above precautions.
Modification
Modifications made to the motorcycle not approved by Yamah a, or t he remo val of original equipme nt,
may render your motorcycle unsafe for use and may cause severe personal injury. Mod ificatio ns 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 ext ra care if riding a motorcycle
which has added cargo or accessories. Here are some genera l guidelines to follow if load ing cargo or
adding accessories to your motorcycle:
1-3
SAFETY INFORMATION
Loading
The total weight of the operator, passenger, accessories and cargo must not exceed the maximum
load limit of 205 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, fr ont 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 b e available, you must personally be respon sible
for the proper selection, installation 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.
1
1-4
SAFETY INFORMATION
a. 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.
1
b. 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 being passed by or passing large vehicles.
c. Certain accessories can displace the operator from his or her normal riding position. This improp-
er position limits the freedom of movement of the operator and may limit control ability. Therefor e
such accessories are not recommended.
2. Caution must be used if adding electrical accessories. If these 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
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 system 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 f umes 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.
3. Always turn off the engine before leaving the motorcycle unattended and remove the ignition key.
When parking the motorcycle, note the following:
1-5
SAFETY INFORMATION
a. The engine and exhaust system 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 a 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. If it should lean over,
gasoline may leak out of the carburetor or fuel tank.
5. If you should swallow any gasoline, inhale a lot of gasoline vapor, or allow gasoline to get in your
eyes, see your doctor immediately. If any gasoline spills on your skin or clothing, immediately wash it
off with soap and water and change your clothes.
