Sidestand
The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cu t-off system, which
cuts the ignition in certain situations.
(See the following section for an expla-
nation of the ignition circuit cut-off sys-
tem.)
WARNING
EWA10242
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly and have a
Yamaha dealer repair it if it does not
function properly.
EAU66771
Ignition circuit cut-off system
The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.
It prevents starting when the side-
stand is up, but neither brake is ap-
plied.
It prevents starting when either
brake is applied, but the sidestand
is still down.
It cuts the running engine when the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-of f system according
to the following procedure.

Starting the engine
NOTICE
ECA10251
See page 7-5 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.
In order for the ignition circuit cut-off
system to enable starting, the sides-
tand must be up. (See page 5-29.) 1. With the smart key turned on, ap- proach the vehicle.
2. Push the “ON/ ” switch.
Upon authentication of the smart
key, the beeper will sound twice
and the centerstand and steering
locks (if applied) will be released.
All indicator and warning lights
should come on briefly and then go
off.
The ABS warning light should
come on when the power of the ve-
hicle is turned on, and go off once
the vehicle reaches a traveling
speed of 10 km/h (6 mi/h) or high-
er.
NOTICE
ECA22510
If a warning or indicator light does
not work as described above, see
page 5-2 for the corresponding warning and indicator light circuit
check.
3. Close the throttle completely.
4. Start the engine by pushing the “ON/ ” switch while applying the
front or rear brake.
If the engine does not start within 5
seconds of pressing the “ON/ ”
switch, wait 10 seconds before
pressing the switch again to allow
the battery voltage to restore.
NOTICE

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
Avoid high engine speeds during
acceleration.
Avoid high engine speeds with no
load on the engine.
Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU16842
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU36532
0–1000 km (0–600 mi)
Avoid prolonged operation above 5100
r/min. NOTICE: After 1000 km (600
mi) of operation, the engine oil must
be changed, and the oil filter car-
tridge or element replaced.
[ECA11283]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 6100
r/min.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE
ECA10311
Keep the engine speed out of
the tachometer red zone.
If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.

Periodic maintenance charts
TIP
Items marked with an asterisk should be performed by your Yamaha dealer
because these items require special tools, data, and technical skills.
From 50000 km (30000 mi), repeat the maintenance intervals starting from
10000 km (6000 mi).
The annual checks must be performed every year, except if a distance-
based maintenance is performed instead.

TIP
Air filters
The engine air filter uses a disposable oil-coated paper element. This element
cannot be cleaned with compressed air, doing so will only damage it.
If you often ride in the rain or in dusty areas, have the engine air filter and V-
belt air filter elements serviced more frequently.
Hydraulic brake service
Regularly check the brake fluid levels in the reservoirs, and refill as necessary.
Replace the internal components of the brake master cylinders and calipers,
and change the brake fluid every 2 years.
Replace the brake hoses every 4 years, or sooner if cracked or damaged.

for coolant leakage. 
