WARNING:
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.
2. Tire inspection
Always check the tires before operating the motorcycle.
If a tire tread shows crosswise lines (minimum tread
depth), if the tire has a nail or glass fragments in it, or if
the side wall is cracked, contact a Yamaha dealer or
other qualified mechanic and have the tire replaced.
