SAFETY INFORMATION
EAU41214
Be a Responsible Owner
As the vehicle’s owner, you are responsible for the safe and proper operation of your motorcycle.
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:
zObtain thorough instructions from a competent source on all aspects of motorcycle operation.
zObserve the warnings and maintenance requirements in this Owner’s Manual.
zObtain qualified training in safe and proper riding techniques.
zObtain professional technical service as indicated in this Owner’s Manual and/or when made necessary by mechanical conditions.
Safe Riding
Perform the pre-operation checks each time you use the vehicle to make sure
it is in safe operating condition. Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment damage. See page 4-1 for a list of pre-operation checks.
zThis motorcycle is designed for offroad use only, therefore, it is illegal to operate it on public streets, roads, or highways, even a dirt or gravel one. Off-road use on public lands may be illegal. Please check local regulations before riding.
zThis motorcycle is designed to carry the operator only. No passengers.
zThe 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:
z Wear a brightly colored jacket.
1 - 1
z Use extra caution when you are approaching and passing through intersections, since intersections
are the most likely places for 1 motorcycle accidents to occur.
zRide where other motorists can see you. Avoid riding in another
motorist’s blind spot.
zMany accidents involve inexperienced operators.
zMake sure that you are qualified and that you only lend your motorcycle to other qualified operators.
zKnow your skills and limits. Staying within your limits may help you to avoid an accident.
zWe recommend that you practice riding your motorcycle
until you have become thoroughly familiar with the motorcycle and all of its controls.
zMany accidents have been caused by error of the motorcycle operator. 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
zRide cautiously in unfamiliar areas. You may encounter hidden obstacles that could cause an
1accident.
zThe posture of the operator 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.
zNever ride under the influence of alcohol or other drugs.
zBe sure the transmission is in neutral before starting the engine.
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.
zAlways wear an approved helmet.
zWear a face shield or goggles.Wind in your unprotected eyes could contribute to an impairment of vision that could delay seeing a hazard.
zThe use of a jacket, heavy boots,
trousers, gloves, etc., is effective in preventing or reducing abrasions or lacerations.
zNever wear loose-fitting clothes, otherwise they could catch on the control levers, footrests, or wheels and cause injury or an accident.
zAlways wear protective clothing that covers your legs, ankles, and feet.The engine or exhaust system become very hot during or after operation and can cause burns.
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide can cause headaches, dizziness, drowsiness, nausea, confusion, and eventually death.
Carbon Monoxide is a colorless, odorless, tasteless gas which may be present even if you do not see or smell any engine exhaust. Deadly levels of carbon monoxide can collect rapidly and you can quickly be overcome and unable to save yourself. Also, deadly levels of carbon monoxide can linger for hours or days in enclosed or poorly ventilated areas. If you experience any symptoms
1 - 2
of carbon monoxide poisoning, leave the area immediately, get fresh air, and SEEK MEDICAL TREATMENT.
zDo not run engine indoors. Even if you try to ventilate engine exhaust with fans or open windows and doors, carbon monoxide can rapidly reach dangerous levels.
zDo not run engine in poorly ventilated or partially enclosed areas such as barns, garages, or carports.
zDo not run engine outdoors where engine exhaust can be drawn into a building through openings such as windows and doors.
Loading
Adding accessories 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 accessories to your motorcycle. Use extra care when riding a motorcycle that has added accessories. Here are some general guidelines to follow if adding accessories to your motorcycle:
SAFETY INFORMATION
Operation of an overloaded vehicle could cause an accident.
zThe weight of the operator must not exceed 150 kg (331 lb).
zAccessory weight should be kept as low and close to the motorcycle as possible. Securely pack your heaviest items as close to the center of the vehicle as possible and make sure to distribute the weight as evenly as possible on both sides of the motorcycle to minimize imbalance or instability.
zShifting weights can create a sudden imbalance. Make sure that accessories are securely attached to the motorcycle before riding.
Check accessory mounts frequently.
zProperly adjust the suspension for your load, and check the condition and pressure of your tires.
zNever attach any large or heavy items to the handlebar, front fork, or front fender.
GenuineYamaha Accessories
Choosing accessories for your vehicle is an important decision. Genuine
Yamaha accessories, which are available only from a Yamaha dealer, have been designed, tested, and approved by Yamaha for use on your vehicle.
Many companies with no connection to Yamaha manufacture parts and accessories or offer other modifications forYamaha vehicles.Yamaha is not in a position to test the products that these aftermarket companies produce. Therefore,Yamaha can neither endorse nor recommend the use of accessories not sold byYamaha or modifications not specifically recommended by Yamaha, even if sold and installed by a Yamaha dealer
Aftermarket Parts, Accessories, and Modifications
While you may find aftermarket products similar in design and quality to genuine Yamaha accessories, recognize that some aftermarket accessories or modifications are not suitable because of potential safety hazards to you or others. Installing aftermarket products or having other modifications performed to your vehicle that change any of the
1 - 3
vehicle’s design or operation characteristics can put you and others at greater risk of serious injury or death.
You are responsible for injuries related 1 to changes in the vehicle.
Keep the following guidelines in mind, as well as those provided under “Loading” when mounting accessories.
zNever install accessories that would impair the performance of your motorcycle. Carefully 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.
zAccessories fitted to the handlebar or the front fork area can create instability due to improper weight distribution. 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.
zBulky or large accessories may seriously affect the stability of the motorcycle.Wind may attempt to
SAFETY INFORMATION
lift the motorcycle, or the motorcycle may become unstable in cross winds.
1 z 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.
zUse caution when adding electrical 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.
AftermarketTires and Rims
The tires and rims that came with your motorcycle were designed to match the performance capabilities and to provide the best combination of handling, braking, and comfort. Other tires, rims, sizes, and combinations may not be appropriate. Refer to page 6-14 for tire specifications and more information on replacing your tires.
