Proper loading of your motorcycle is important for the
handling, braking, and other performance and safety
characteristics of your motorcyle. Do not carry loosely
packed items that can shift. Securely pack your
heaviest items close to the center of the motorcycle,
and distribute the weight evenly from side to side.
Properly adjust the suspension for your load, and
check the condition and pressure of your tires. NEVER
OVERLOAD YOUR MOTORCYCLE. Make sure the total
weight of the cargo, rider, passenger, and accessories
(fairing, saddlebags, etc. if approved for this model)
does not exceed the maximum load of the motorcycle.
Operation of an overloaded motorcycle could cause
tire damage, an accident, or even injury.

WARNING:

4-6
1. It is dangerous to ride with a worn-out tire. When
the tire tread begin to show signs of wear, replace
the tire immediately. Brakes, tires and related wheel
parts should be left to a Yamaha dealer.
2. Patching a punctured tube is not recommended. If
it is absolutely necessary to do so, use great care
and replace the tube as soon as possible with a
good quality replacement.
Fitting/Fasteners
Alway check the tightness of chassis fittings and fasteners
before a ride. Use the chart on page 6-5 to find the correct
torque.
Switches
Check the operation of the starter switch, main switch,
ì Engine Stopî switch.
WARNING:Wheels
To ensure maximum performance, long service, and safe
operation, note the following:
1. Always inspect the wheels before a ride. Check for
cracks, bends, or warpage of the wheel; be sure the
spokes are tight and undamaged. If any abnormal
condition exists in a wheel, consult a Yamaha dealer or
other qualified mechanic. Do not attempt even small
repairs to the wheel. If a wheel is deformed or cracked,
it must be replaced.
2. Tires and wheels should be balanced whenever either
one is changed or replaced. Failure to have a wheel
balanced can result in poor performance, adverse
handling characteristics, and shortened tire life.
3. After installing a tire, ride conservatively to allow the
tire to seat itself on the rim properly. Failure to allow
proper seating may cause tire failure, resulting in
damage to the motorcycle and injury to the rider.
