Adjusting the front fork
1. Spring preload adjusting bolt
(a) Increasing the spring preload
(b) Decreasing the spring preload
This front fork is equipped with spring
preload adjusting bolt.
EWA10180
WARNING0
Always adjust both fork legs equal-
ly, otherwise poor handling and
loss of stability may result.
Adjust the spring preload as follows.
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolts on each fork leg in
direction (a). To decrease the spring
preload and thereby soften the sus-
pension, turn the adjusting bolts on
each fork leg in direction (b).Maximum (hard):
0 complete turns in direction (b)*
Standard:
22 complete turns in direction (b)*
Minimum (soft):
27 complete turns in direction (b)*
* With the adjusting bolt fully turned in
direction (a)
TIP
Use the 10 mm hexagon wrench in-
cluded in the owner’s tool kit to turn
the adjusting bolts.

Never adjust the spring preload un-
til the exhaust system has cooled

EWA10221
WARNING0
This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.
●Do not tamper with or attempt
to open the cylinder assembly.
●Do not subject the shock ab-
sorber assembly to an open
flame or other high heat
source. This may cause the unit
to explode due to excessive
gas pressure.
●Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.
●Do not dispose of a damaged
or worn-out shock absorber
assembly yourself. Take the
shock absorber assembly to a
Yamaha dealer for any service.

WARNING0
The vehicle must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up),
otherwise the sidestand could con-
tact the ground and distract the
operator, resulting in a possible
loss of control. Yamaha’s ignition
circuit cut-off system has been de-
signed to assist the operator in ful-
filling the responsibility of raising
the sidestand before starting off.
Therefore, check this system regu-
larly as described below and have
a Yamaha dealer repair it if it does
not function properly.
EAU15301
Sidestand
1. 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.
TIP
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situa-
tions. (See further down for an expla-
nation of the ignition circuit cut-off sys-
tem.)

Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch,
clutch switch and neutral switch) has
the following functions.
●It prevents starting when the
transmission is in gear and the
sidestand is up, but the clutch
lever is not pulled.
●It prevents starting when the
transmission is in gear and the
clutch lever is pulled, but the side-
stand is still down.
●It cuts the running engine when
the transmission is in gear and
the sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system accord-
ing to the following procedure.
TIP
This check is most reliable if per-
formed with a warmed-up engine.

OPERATION AND IMPORTANT RIDING POINTS
EAU15951
Read the Owner's Manual carefully to
become familiar with all controls. If
there is a control or function you do not
understand, ask your Yamaha dealer.
EWA10271
WARNING0
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.

EAU48020
TIP
This model is equipped with a lean an-
gle sensor to stop the engine in case
of a turnover. In this case, the multi-
function display indicates error code
30, but this is not a malfunction. Turn
the key to "OFF" and then to "ON" to
clear the error code. Failing to do so
will prevent the engine from starting
even though the engine will crank
when pushing the start switch.
EAUB1570
Starting the engine
In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
●The transmission is in the neutral
position.
●The transmission is in gear with
the clutch lever pulled and the
sidestand up.
EWA10290
WARNING0
●Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure de-
scribed on page 4-18.
●Never ride with the sidestand
down.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “
I”.

OPERATION AND IMPORTANT RIDING POINTS
3. Start the engine by pushing the
start switch.
TIP
If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the en-
gine more than 10 seconds on any one
attempt.
ECA11040
NOTICE
For maximum engine life, never ac-
celerate hard when the engine is
cold!
TIP
The engine is warm when it quickly re-
sponds to the throttle.
EAU16671
Shifting
1. Shift pedal
N. Neutral position
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.
