TIPThis model is equipped with:
 an inertial measurement unit
(IMU). This unit stops the engine in
case of a turnover. Turn the main
switch off and then on before at-
tempting to restart the engine.
Failing to do so will prevent the en-
gine from starting even though the
engine will crank when pushing
the start switch.
 an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. If the engine
stops, simply push the start
switch to restart the engine.

Shiftin gShifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing hills,
etc. The gear positions are shown in
the illustration.TIPTo shift the transmission into the
neutral position ( ), press the
shift pedal down repeatedly until it
reaches the end of its travel, and
then slightly raise it.
 This model is equipped with a
quick shift system. (See page 3-3.)
NOTICE

Even with the transmission in
the neutral position, d o not
coast for lon g period s of time
with the en gine off, nor tow the
motorcycle for long d istances.
The transmission is properly lu-
b ricated only when the en gine is
running . Inadequate lu brication
may damag e the transmission.
 Except when usin g the quick
shift system, always pull the
clutch lever when chan gin g

EAU85380
To decelerate
1. Release the throttle and apply both the front and the rear brakes
smoothly to slow the motorcycle.
2. As the vehicle decelerates, shift to a lower gear.
3. When the engine is about to stall or runs roughly, pull the clutch le-
ver in, use the brakes to slow the
motorcycle, and continue to
downshift as necessary.
4. Once the motorcycle has stopped, the transmission can be
shifted into the neutral position. The neutral indicator light should
come on and then the clutch lever
can be released.
WARNING


Improper brakin g can cause
loss of control or traction. Al-
ways use b oth brakes an d apply
them smoothly.
 Make sure that the motorcycle
and the en gine have sufficiently
slowe d b efore shiftin g to a low-
er gear. En gag in g a lower gear
when the vehicle or en gine
speed is too hi gh coul d make
the rear wheel lose traction or
the en gine to over-rev. This
coul d cause loss of control, an
acci dent an d injury. It coul d also
cause en gine or drive train dam-
a g e.

Tips for re ducin g fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
 Shift up swiftly, and avoid high en-
gine speeds during acceleration.
 Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the en-
gine.
 Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).

Why Yamalu
beYAMALUBE oil is a Genuine YAMAHA
Part born of the engineers’ passion
and belief that engine oil is an impor-
tant liquid engine component. We form
teams of specialists in the fields of me-
chanical engineering, chemistry, elec-
tronics and track testing, and have
them develop the engine together with
the oil it will use. Yamalube oils take full
advantage of the base oil’s qualities
and blend in the ideal balance of addi-
tives to make sure the final oil clears
our performance standards. Thus,
Yamalube mineral, semisynthetic and
synthetic oils have their own distinct
characters and value. Yamaha’s expe-
rience gained over many years of re-
search and development into oil since
the 1960’s helps make Yamalube the
best choice for your Yamaha engine.
