Q GIVE SAFETY THE RIGHT OF WAY
Motorcycles are fascinating vehicles, which can give you an unsurpassed feeling of power and freedom. However, they also impose certain limits, which you must accept; even the best motorcycle
does not ignore the laws of physics.
1
Regular care and maintenance are essential for preserving value and operating condition of your
motorcycle. Moreover, what is true for the motorcycle is also true for the rider: good performance
depends on being in good shape. Riding under the influence of medication, drugs and alcohol is, of
course, out of the question. Motorcycle riders—more than car drivers—must always be at their mental
and physical best. Under the influence of even small amounts of alcohol, there is a tendency to take
dangerous risks.
Protective clothing is as essential for the motorcycle rider as seat belts are for car drivers and passengers. Always wear a complete motorcycle suit (whether made of leather or tear-resistant synthetic
materials with protectors), sturdy boots, motorcycle gloves and a properly fitting helmet. Optimum protective wear, however, should not encourage carelessness. Although full-coverage helmets and suits,
in particular, create an illusion of total safety and protection, motorcyclists will always be vulnerable.
Riders who lack critical self-control run the risk of going too fast and are apt to take chances. This is
even more dangerous in wet weather. The good motorcyclist rides safely, predictably and defensively
—avoiding all dangers, including those caused by others.
Enjoy your ride!

other high heat sources, otherwise it may explode due to
excessive gas pressure.
8 Do not deform or damage the
gas cylinder in any way, as
this will result in poor damping performance.
8 Always have a Yamaha dealer
service the shock absorber.

YPVS
This model is equipped with the
YPVS (Yamaha Power Valve
System). This system boosts engine
performance and efficiency by means
of a variable valve in the exhaust
port. The YPVS valve is constantly
adjusted in accordance with the
engine speed by a computer-controlled servomotor.
Since the YPVS is an important part
of the engine and requires very
sophisticated adjustment, have a
Yamaha dealer, who has the necessary professional knowledge and
experience, make this adjustment.
EC000023
cC
The YPVS has been set and extensively tested at the Yamaha factory. Changing these settings without sufficient technical knowledge
may result in poor performance of
or damage to the engine.
YPVS operation noises can be heard
in the following instances:
8 When the key is turned to “ON”
and the engine is started.
8 When the engine stalls with the
key in the “ON” position.
EC000024

If the YPVS does not operate, have
a Yamaha dealer check it.

Sidestand
The sidestand is located on the left
side of the frame. Raise the sidestand or lower it with your foot while
holding the motorcycle upright.
NOTE:
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situations. (See further down for an
explanation of the ignition circuit cutoff system.)

The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly, even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thor-

ough visual inspection, to check the following points before each ride.
