EAU53920
Traveling distance TIPThe distance that can be traveled on a
single charge varies according to the
riding and road conditions.
These conditions include the number of
starts and stops, vehicle load, the
steepness of slopes, road conditions,
wind direction and velocity, ambient
temperature, charging status, de-
creased battery performance, and lowtire air pressure.
Distance traveled on a single
charge
The data in the following chart was
measured at Yamaha Motor Co., Ltd. It
was measured when traveling with a
new battery at an ambient temperature
and vehicle load (total weight of rider
and luggage) as shown below on a dry
road surface in the absence of wind.
TIPThe maximum slope ascending capac-
ity is a gradient of approximately 16%(about 9 degrees).
Because of the battery character,
the riding distance might be re-

tery falls below a specified temper-ature, “COOL” flashes.
TIP
When the temperature of the bat-
tery exceeds a specified tempera-
ture, “HEAT” flashes and the
driving power is reduced to limit
the electric output from the battery,
but this is normal.

When the temperature of the bat-
tery falls below a specified temper-
ature, “COOL” flashes and the
driving power is reduced to limit
the electric output from the battery,
but this is normal.

If the vehicle is ridden for an ex-
tended period in high tempera-
tures, “HEAT” may flash and the
riding speed may be reduced.

If the vehicle is ridden after it has
been left in a hot place or under di-
rect sunlight, “HEAT” may flash
and the riding speed may be re-
duced.


The battery may be above the
maximum 50 
C suitable for charg-
ing immediately after riding. In this
case, the charger enters a waiting
mode and “HEAT” flashes until the

the specified temperature. Charg-
ing then starts automatically.

