SAFETY INFORMATION
TWO-WHEELED MACHINES 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. HE OR
SHE SHOULD:
1. OBTAIN THOROUGH INSTRUCTIONS FROM A COMPETENT SOURCE ON ALL ASPECTS OF
MACHINE OPERATION.
2. OBSERVE THE WARNINGS AND MAINTENANCE REQUIREMENTS IN THE OWNERÕS MANUAL.
3. OBTAIN QUALIFIED TRAINING IN SAFE AND PROPER RIDING TECHNIQUES.
4. OBTAIN PROFESSIONAL TECHNICAL SERVICE AS INDICATED BY THE OWNERÕS 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 machine is designed for off-road use only. It is illegal for this machine to be operated on any public
street, road, or highway. Off-road use on public lands may be illegal. Please check local regulations before riding.
3. This machine is designed to carry the operator only. No passengers.
4. Many accidents involve inexperienced operators.
a. Know your skills and limits. Staying within your limits may help you to avoid an accident.
b. Only lend your machine to experienced operators.
5. Many machine accidents have been caused by machine 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). Never travel faster than warranted by conditions.

SAFETY INFORMATION
6. Ride cautiously in unfamiliar areas. You may encounter hidden obstacles which could cause an accident.
7. The operatorÕs 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 maintain control of the machine.
8. Never ride under the influence of alcohol or drugs.
Protective apparel
The majority of fatalities from machine 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.
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 can
cause burns. Always wear protective clothing that covers your legs, ankles, and feet.
Modification
Modifications made to the machine not approved by Yamaha, or the removal of original equipment, may
render your machine unsafe for use and may cause severe personal injury. Modifications may also make
your machine illegal to use.

SAFETY INFORMATION
Loading and accessories
Adding accessories or cargo to your machine 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 machine. Use extra care if riding a machine which has added
cargo or accessories. Genuine Yamaha accessories have been specifically designed for use on this machine. Since Yamaha cannot test all other accessories which may be available, you must personally be responsible 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 ÒLOADINGÓ.
1. Never install accessories or carry cargo that would impair the performance of your machine. 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 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.
b. Bulky or large accessories may seriously affect the stability of the machine due to aerodynamic ef-
fects. Wind may attempt to lift the machine, or the machine 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 improper
position limits the freedom of movement of the operator and may limit control ability. Therefore
such accessories are not recommended.
1-3
SAFETY INFORMATION
2. Caution must be used if adding electrical accessories. If these accessories exceed the capacity of the
machineÕs 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 fumes are poisonous and may cause loss of consciousness and death within a short time. Always operate your machine in an area that has adequate ventilation.
3. Always turn off the engine before leaving the machine unattended and remove the ignition key. When
parking the machine, note the following:
a. The engine and exhaust system may be hot. Park the machine in a place where pedestrians or chil-
dren are not likely to touch these hot areas.
b. Do not park the machine on a slope or soft ground; the machine may fall over.
c. Do not park the machine near a flammable source, e.g. a kerosene heater, or near an open flame.
The machine could catch fire.
4. When transporting the machine in another vehicle, be sure it is kept upright and that the fuel cock is
turned to ÒONÓ or ÒRESÓ (for vacuum type)/ÒOFFÓ (for manual type). 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.
