Shifting
Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing hills,
etc.
The gear positions are shown in the il-
lustration.
TIP
To shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it.
NOTICE
ECA10261
Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long dis-
tances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.
Always use the clutch while
changing gears to avoid dam-
aging the engine, transmission,and drive train, which are not
designed to withstand the
shock of forced shifting.
EAU16682To start out and accelerate
1. Pull the clutch lever to disengage
the clutch.
2. Shift the transmission into first
gear. The neutral indicator light
should go out.
3. Open the throttle gradually, and at
the same time, release the clutch
lever slowly.
4. At the recommended shift points
shown in the following table, close
the throttle, and at the same time,
quickly pull the clutch lever in.
5. Shift the transmission into second
gear. (Make sure not to shift the
transmission into the neutral posi-
tion.)
6. Open the throttle part way and
gradually release the clutch lever.
7. Follow the same procedure when
shifting to the next higher gear.
TIP
When shifting gears in normal operat-
ing conditions, use the recommended
shift points.
EAU58270To decelerate
1. Release the throttle and apply
both the front and the rear brakes
smoothly to slow the motorcycle.
2. At the recommended shift points
shown in the following table, shift
to a lower gear.
3. When the motorcycle reaches 20
km/h (12 mi/h), the engine is about
to stall or runs roughly, pull the
1. Shift pedal
2. Neutral position

5 clutch lever 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
EWA17380
Improper braking can cause
loss of control or traction. Al-
ways use both brakes and apply
them smoothly.
Make sure that the motorcycle
and the engine have sufficiently
slowed before shifting to a low-
er gear. Engaging a lower gear
when the vehicle or engine
speed is too high could make
the rear wheel lose traction or
the engine to over-rev. This
could cause loss of control, an
accident and injury. It could also
cause engine or drive train dam-
age.
EAU64150Recommended shift points
The recommended shift points during
acceleration and deceleration are
shown in the table below.

Tips for reducing fuel con-
sumption
Fuel 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).
Shift up points:
1st → 2nd: 20 km/h (12 mph)
2nd → 3rd: 30 km/h (19 mph)
3rd → 4th: 40 km/h (25 mph)
4th → 5th: 50 km/h (31 mph)
5th → 6th: 60 km/h (37 mph)
Shift down points:
6th → 5th: 45 km/h (28 mph)
5th → 4th: 35 km/h (22 mph)
4th → 3rd: 25 km/h (16 mph)

Drive chain slack
The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU60046To check the drive chain slack
1. Place the motorcycle on the side-
stand.
TIP
When checking and adjusting the drive
chain slack, there should be no weight
on the motorcycle.
2. Shift the transmission into the
neutral position.
3. Push down on the drive chain un-
der the end of the drive chain
guard.
4. Measure distance A between the
drive chain guard and the center
of the chain as shown.
5. If distance A is incorrect, adjust it
as follows. NOTICE: Improper
drive chain slack will overload
the engine as well as other vital
parts of the motorcycle and canlead to chain slippage or break-
age. If distance A is more than
58.0 mm (2.28 in), the chain can
damage the frame, swingarm,
and other parts. To prevent this
from occurring, keep the drive
chain slack within the specified
limits.
[ECA23070]
EAU74260
To adjust the drive chain slack
Consult a Yamaha dealer before ad-
justing the drive chain slack.
1. Loosen the axle nut and the lock-
nut on each side of the swingarm.
2. To tighten the drive chain, turn the
drive chain slack adjusting bolt on
each side of the swingarm in di-
rection (a). To loosen the drive
chain, turn the adjusting bolt on
each side of the swingarm in di-
rection (b), and then push the rear
wheel forward.
