Odometer “Odo”
The odometer has two functions.
8It shows the total distance trav-
eled.
8It automatically changes to the
fuel tripmeter mode “Trip F”
when the fuel level reaches
approximately 2.0 L. (See “Fuel
tripmeter” for details.)
NOTE:
If the odometer indicates “––––––”,
have a Yamaha dealer check or
repair the multi-function display as it
may be faulty.

Fuel tripmeter “Trip F”
When the fuel level reaches approxi-
mately 2.0 L, the odometer display
automatically changes to the fuel trip-
meter mode “Trip F” and starts count-
ing the distance traveled from that
point. After refueling and traveling
5 km, the odometer display returns to
“Odo”.To return to the odometer mode
before refueling, push the “SELECT”
button until “Trip F” begins flashing
(“Trip F” will only flash for five sec-
onds). While “Trip F” is flashing, push
the “RESET” button for at least one
second and the display will return to
the odometer mode. From that time,
both “Trip” and “Odo” are displayed
until you refuel and travel 5 km.
NOTE:
The display cannot be changed back
to “Trip F” after pushing the “RESET”
button.

ABSABSThe Yamaha ABS (Anti-lock Brake
System) features a dual electronic
control system, which acts on the
front and rear brakes independently.
The ABS securely controls wheel
lockup during emergency braking on
changing road surfaces and under
various weather conditions, thereby
maximizing tire adhesion and perfor-
mance while providing a smooth
braking action. The ABS is monitored
by an ECU (Electronic Control Unit),
which will have recourse to manual
braking if a malfunction occurs.

The ABS performs best on
long braking distances.
8 8
On certain (rough or gravel)
roads, the braking distance
may be longer with than with-
out the ABS. Therefore, always
keep a sufficient distance to
the vehicle ahead to match the
riding speed.
NOTE:
8When the ABS is activated, the
brakes are operated in the usual
way. A pulsating action may be
felt at the brake levers, but this
does not indicate a malfunction.
8This ABS has a test mode which
allows the owner to experience
the pulsating at the brake levers
when the ABS is operating.
However, special tools are
required, so please consult your
Yamaha dealer when performing
this test.
