ACCESSORIES AND LOADING
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 acessories. 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 “LOADING”.
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 effects. 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.
2. Caution must be used if adding electrical accessories. If these accessories exceed the capacity of the machine’s electrical
system, an electric failure could result, which could cause a dangerous loss of lights or engine power.

NOTE:
Pre-operation checks should be made each time the motorcycle is used. Su\
ch an inspection can be thoroughly accomplished
in a very short time; and the added safety it assures is more than worth\
the time involved. If any maintenance service or
adjustment is needed, consult the chart above to refer to the pages in w\
hich the service or adjustment is described.
1. The engine, exhaust pipe, and muffler will be very hot after the engine \
has been run.
Be careful not to touch them or to allow any clothing item to contact th\
em during inspection or repair.
2. If any item is not working properly, have it inspected and repaired before operating the motorcycle.

Tips for reducing fuel consumption
Your motorcycle’s fuel consumption depends to a large
extent on your riding style. The following tips can help reduce
fuel consumption.
1. Warm up the engine before riding.
2. Turn off the starter lever as soon as possible.
3. Shift up swiftly and avoid high engine speeds during
acceleration.
4. Do not double-clutch or rev the engine while shifting down and avoid high engine speeds with no load engine.
5. Turn off the engine instead of letting it idle for an extended lenght of time, i.e. in traffic jams, at traffic lights or railroad
crossings. Engine Break-in
There is never a more important period in the life of your
motorcycle than the period 1.000Km. For this reason we
ask that you carefully read the following material. Because
the engine is brand new, you must not put an excessive
load on it for the first several hours of running.
During this period, prolonged full throttle operation, or any
condition which might result in excessive heating of the
engine must be avoided.
1. 0 ~ 150 Km:
Avoid operation above 1/3 throttle. Stop the engine and
let it cool for 5 to 10 minutes after every hour of
operation. Vary the speed of the motorcycle from time
to time. Do not operate it at one set throttle position.
