Speed
ometer
The speedometer shows the vehicle’s
traveling speed.
Clock
The clock uses a 12-hour time system.
To set the clock
1. Turn the key to “ON”.
2. Push the “SELECT” button and “RESET” button together for at
least two seconds.
3. When the hour digits start flash- ing, push the “RESET” button to
set the hours.
4. Push the “SELECT” button, and
the minute digits will start flashing.
5. Push the “RESET” button to set the minutes.
6. Push the “SELECT” button and then release it to start the clock. Fuel meter
The fuel meter indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel meter disappear to-
wards “E” (Empty) as the fuel level
decreases. When the last segment and
fuel level warning indicator “ ” start
flashing, refuel as soon as possible.
TIP
If a problem is detected in the electrical
circuit, the following cycle is repeated
until the malfunction is corrected: fuel
level segments and fuel level warning
indicator “ ” flash eight times, then go
off for approximately 3 seconds. Have
a Yamaha dealer check the electrical
circuit.

3 Instantaneous fuel consumption
meter
This meter shows the instantaneous
fuel consumption.
Depending on the display setting se-
lected for the instantaneous fuel con-
sumption mode “F/ECO”, the
displayed segments increase or de-
crease.
 km/L and MPG (for the UK): The
number of segments displayed in-
creases the more efficiently the
vehicle is being operated.
 L/100 km: The number of seg-
ments displayed decreases the
more efficiently the vehicle is be-
ing operated.
Multi-function display
The multi-function display is equipped
with the following: 
an odometer
 two tripmeters (which show the
distance traveled since they were
last set to zero)
 a fuel reserve tripmeter (which
shows the distance traveled since
the last segment of the fuel meter
started flashing)
 an instantaneous fuel consump-
tion display
 an average fuel consumption dis-
play
 an oil change tripmeter
 a V-belt replacement tripmeter
 an oil change indicator
 a V-belt replacement indicator
Except for the UK:
Push the “SELECT” button to switch
the display between the odometer
mode “ODO”, tripmeter modes “TRIP
1” and “TRIP 2”, oil change tripmeter
mode “OIL TRIP”, V-belt replacement
tripmeter mode “V-BELT TRIP”, in-
stantaneous fuel consumption mode
“F/ECO” (km/L or L/100 km), and aver-
age fuel consumption mode “AVE
F/ECO” (km/L or L/100 km) in the fol-
lowing order:
ODO → TRIP 1 → TRIP 2 → OIL TRIP
→ V-BELT TRIP → F/ECO → AVE
F/ECO → ODO
For the UK:
Push the “SELECT” button to switch
the display between the odometer
mode “ODO”, tripmeter modes “TRIP
1” and “TRIP 2”, oil change tripmeter
mode “OIL TRIP”, V-belt replacement
tripmeter mode “V-BELT TRIP”, in-
stantaneous fuel consumption mode

lowing order:
ODO
→ TRIP 1 → TRIP 2 → OIL TRIP
→ V-BELT TRIP → F/ECO → AVE
F/ECO → ODO
If the fuel level warning indicator “ ”
and last segment of the fuel meter start
flashing, the display automatically
changes to the fuel reserve tripmeter
mode “TRIP F” and starts counting the
distance traveled from that point. In
that case, push the “SELECT” button
to switch the display between the vari-
ous tripmeter, odometer, oil change
tripmeter, V-belt replacement tripme-
ter, instantaneous fuel consumption
and average fuel consumption modes
in the following order:
TRIP F → TRIP 1 → TRIP 2 → OIL TRIP
→ V-BELT TRIP → F/ECO → AVE
F/ECO → ODO → TRIP F
To reset a tripmeter, select it by push-
ing the “SELECT” button, and then
push the “RESET” button for at least
one second.
TIP
 If you do not reset the fuel reserve
tripmeter manually, it resets itself
automatically and the display re-
turns to the prior mode after refu-
eling and traveling 5 km (3 mi).
 If you do not reset tripmeters 1
and 2, they will reset to 0 and con-
tinue counting after 9999.9 has
been reached. 
The odometer will lock at 999999
and cannot be reset.
Instantaneous fuel consumption
mo de
The instantaneous fuel consumption
display can be set to either “km/L” or
“L/100 km”, and either “MPG” or
“L/100 km” (for the UK).  “km/L”: The distance that can be
traveled on 1.0 L of fuel under the
current riding conditions is shown.
 “L/100 km”: The amount of fuel
necessary to travel 100 km under
the current riding conditions is
shown.
 “MPG”: The distance that can be
traveled on 1.0 lmp. gal of the fuel
under the current riding conditions
is shown.
To switch between the instantaneous
fuel consumption display settings,
push the “SELECT” button for one sec-
ond.
TIP
 If traveling at speeds under 10
km/h (6 mi/h), “_ _._” is displayed.
 When MPG is selected, no units
indicator will be displayed.

Vehicle data recor din g
This model’s ECU stores certain vehi-
cle data to assist in the diagnosis of
malfunctions and for research and de-
velopment purposes. This data will be
uploaded only when a special Yamaha
diagnostic tool is attached to the vehi-
cle, such as when maintenance checks
or service procedures are performed.
Although the sensors and recorded
data will vary by model, the main data
points are:
 Vehicle status and engine perfor-
mance data
 Fuel-injection and emission-relat-
ed data
Yamaha will not disclose this data to a third party except:  With the consent of the vehicle
owner
 Where obligated by law
 For use by Yamaha in litigation
 For general Yamaha-conducted
research purposes when the data
is not related to an individual vehi-
cle nor owner
