SAFETY INFORMATION

EAU10281
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: G OBTAIN THOROUGH INSTRUCTIONS FROM A COMPETENT SOURCE ON ALL ASPECTS OF MOTORCYCLE OPERATION. G OBSERVE THE WARNINGS AND MAINTENANCE REQUIREMENTS IN THE OWNERS MANUAL. G OBTAIN QUALIFIED TRAINING IN SAFE AND PROPER RIDING TECHNIQUES. G OBTAIN PROFESSIONAL TECHNICAL SERVICE AS INDICATED BY THE OWNERS MANUAL
AND/OR WHEN MADE NECESSARY BY MECHANICAL CONDITIONS.
Safe riding G Always make pre-operation checks. Careful checks may help prevent an accident. G This motorcycle is designed to carry the operator and a passenger. G 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 you are approaching and passing through intersections, since intersections are the most likely places for motorcycle accidents to occur.
Ride where other motorists can see you. Avoid riding in another motorists blind spot. Many accidents involve 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 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). 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, the 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 onroad use only. 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. G Always wear an approved helmet. G Wear a face shield or goggles. Wind in your unprotected eyes could contribute to an impairment of vision that could delay seeing a hazard. G The use of a jacket, heavy boots, trousers, gloves, etc., is effective in preventing or reducing abrasions or lacerations. G Never wear loose-fitting clothes, otherwise they could catch on the control levers, footrests, or wheels and cause injury or an accident. G 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. A passenger should also observe the above precautions.
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:
U5WME5E0.book Page 3 Wednesday, December 5, 2007 10:30 AM
Loading The total weight of the operator, passenger, accessories and cargo must not exceed the maximum load limit.
Maximum load: 205 kg (452 lb)
When loading within this weight limit, keep the following in mind: G 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. G Shifting weights can create a sudden imbalance. Make sure that accessories and cargo are securely attached to the motorcycle before riding. Check accessory mounts and cargo restraints frequently. G Never attach any large or heavy items to the handlebar, front fork, or front fender. These items, including such cargo as sleeping

Cast wheels

To maximize the performance, durability, and safe operation of your vehicle, note the following points regarding the specified wheels. G The wheel rims should be checked for cracks, bends or warpage before each ride. If any damage is found, have a Yamaha dealer replace the wheel. Do not attempt even the smallest repair to the wheel. A deformed or cracked wheel must be replaced. G The wheel should be balanced whenever either the tire or wheel has been changed or replaced. An unbalanced wheel can result in poor performance, adverse handling characteristics, and a shortened tire life. G Ride at moderate speeds after changing a tire since the tire surface must first be broken in for it to develop its optimal characteristics.
Since this model is equipped with a hydraulic clutch, adjusting the clutch lever free play is not needed. However, it is necessary to check the clutch fluid level and check the hydraulic system for leakage before each ride. If the clutch lever free play does become excessive, and shifting becomes rough or clutch slippage occurs, causing poor acceleration, there may be air in the clutch system. If there is air in the hydraulic system, have a Yamaha dealer bleed the system before operating the motorcycle.
Adjusting the rear brake light switch
1. Rear brake light switch 2. Rear brake light switch adjusting nut
The rear brake light switch, which is activated by the brake pedal, is properly adjusted when the brake light comes on just before braking takes effect. If necessary, adjust the brake light switch as follows. 1. Remove panel A. (See page 6-6.) 2. Turn the adjusting nut while holding the rear brake light switch in place. To make the brake light come on earlier, turn the adjusting nut in direction (a). To make the brake light come on later, turn the adjusting nut in direction (b).

EAU22321
Checking the front and rear brake pads
The front and rear brake pads must be checked for wear at the intervals specified in the periodic maintenance and lubrication chart. Each brake pad is provided with a wear indicator groove, which allows you to check the brake pad wear without having to disassemble the brake. To check the brake pad wear, check the wear indicator grooves. If a brake pad has worn to the point that the wear indicator groove has almost disappeared, have a Yamaha dealer replace the brake pads as a set. 6

EAU22680

Checking the brake and clutch fluid levels
When checking the fluid level, make sure that the top of the brake or clutch fluid reservoir is level. Use only the recommended quality brake fluid, otherwise the rubber seals may deteriorate, causing leakage and poor braking or clutch performance.

1. Minimum level mark

Recommended brake and clutch fluid: DOT 4 brake fluid
Insufficient brake fluid may allow air to enter the brake or clutch systems, possibly causing them to become ineffective. Before riding, check that the brake fluid is above the minimum level mark and replenish if necessary. A low brake fluid level may indicate worn brake pads and/or brake system leakage. If the brake level is low, be sure to check the brake pads for wear and the brake system for leakage. NOTE: The rear brake fluid reservoir is located behind panel A. (See page 6-6.) Observe these precautions:
Refill with the same type of brake fluid. Mixing fluids may result in a harmful chemical reaction and lead to poor braking or clutch performance. The brake or clutch fluid reservoir diaphragm will lose its shape from the negative pressure if the fluid level goes down too far. Be sure to return the diaphragm to its original shape before installing it into the brake or clutch fluid reservoir. Be careful that water does not enter the brake or clutch fluid reservoir when refilling. Water will
significantly lower the boiling point of the fluid and may result in vapor lock. Brake fluid may deteriorate painted surfaces or plastic parts. Always clean up spilled fluid immediately. As the brake pads wear, it is normal for the brake fluid level to gradually go down. However, if the brake fluid level goes down suddenly, have a Yamaha dealer check the cause.

EAU22750 EAU22760

Changing the brake and clutch fluids
Have a Yamaha dealer change the brake and clutch fluids at the intervals specified in the NOTE after the periodic maintenance and lubrication chart. In addition, have the oil seals of the brake and clutch master cylinders and calipers as well as the brake and clutch hoses replaced at the intervals listed below or whenever they are damaged or leaking. G Oil seals: Replace every two years. G Brake and clutch hoses: Replace every four years.

Drive chain slack

The drive chain slack should be checked before each ride and adjusted if necessary.

EAU22793

To check the drive chain slack 1. Place the motorcycle on the centerstand. 2. Shift the transmission into the neutral position. 3. Spin the rear wheel several times to locate the tightest portion of the drive chain. 4. Measure the drive chain slack as shown.

1. Drive chain slack

Drive chain slack: 20.030.0 mm (0.791.18 in) Tightening torques: Locknut: 16 Nm (1.6 mkgf, 11 ftlbf) Axle nut: 150 Nm (15.0 mkgf, 110 ftlbf)
5. If the drive chain slack is incorrect, adjust it as follows.

EAU34312

To adjust the drive chain slack 1. Loosen the axle nut and the locknut on each side of the swingarm. 2. To tighten the drive chain, turn the drive chain slack adjusting bolt on each side of the swingarm in direction (a).

Troubleshooting
Although Yamaha motorcycles receive a thorough inspection before shipment from the factory, trouble may occur during operation. Any problem in the fuel, compression, or ignition systems, for example, can cause poor starting and loss of power. The following troubleshooting chart represents a quick and easy procedure for checking these vital systems yourself. However, should your motorcycle require any repair, take it to a Yamaha dealer, whose skilled technicians have the necessary tools, experience, and know-how to service the motorcycle properly. Use only genuine Yamaha replacement parts. Imitation parts may look like Yamaha parts, but they are often inferior, have a shorter service life and can lead to expensive repair bills.

While the open design of a motorcycle reveals the attractiveness of the technology, it also makes it more vulnerable. Rust and corrosion can develop even if high-quality components are used. A rusty exhaust pipe may go unnoticed on a car, however, it detracts from the overall appearance of a motorcycle. Frequent and proper care does not only comply with the terms of the warranty, but it will also keep your motorcycle looking good, extend its life and optimize its performance. Before cleaning 1. Cover the muffler outlet with a plastic bag after the engine has cooled down. 2. Make sure that all caps and covers as well as all electrical couplers and connectors, including the spark plug caps, are tightly installed. 3.

CAUTION: Some models are equipped with matte colored finished parts. Be sure to consult a Yamaha dealer for advice on what products to use before cleaning the vehicle. Using a brush, harsh chemical products or cleaning compounds when cleaning these parts will scratch or damage their surface. Wax also should not be applied to any matte colored finished parts.

3. Perform the following steps to protect the cylinders, piston rings, etc. from corrosion. a. Remove the spark plug caps and spark plugs. b. Pour a teaspoonful of engine oil into each spark plug bore. c. Install the spark plug caps onto the spark plugs, and then place the spark plugs on the cylinder head so that the electrodes are grounded. (This will limit sparking during the next step.) d. Turn the engine over several times with the starter. (This will coat the cylinder walls with oil.) e. Remove the spark plug caps from the spark plugs, and then install the spark plugs and the spark plug caps.

WARNING To prevent damage or injury from sparking, make sure to ground the spark plug electrodes while turning the engine over.
4. Lubricate all control cables and the pivoting points of all levers and pedals as well as of the sidestand/centerstand. 5. Check and, if necessary, correct the tire air pressure, and then lift the motorcycle so that both of its wheels are off the ground. Alternatively, turn the wheels a little every month in order to prevent the tires from becoming degraded in one spot. 6. Cover the muffler outlet with a plastic bag to prevent moisture from entering it. 7. Remove the battery and fully charge it. Store it in a cool, dry place and charge it once a month. Do not store the battery in an excessively cold or warm place [less than 0 C (30 F) or more than 30 C (90 F)]. For more information on storing the battery, see page 6-26. NOTE: Make any necessary repairs before storing the motorcycle.
