Tachometer
1. Tachometer
2. Red zone
The tachometer allows the rider to
monitor the engine speed and keep it
within the ideal power range.
When the key is turned to "ON", the
tachometer needle will sweep once
across the r/min range and then return
to zero r/min in order to test the elec-
trical circuit.
ECA10030CAUTION:
Do not operate the engine in the
tachometer red zone.
Red zone: 7,500 r/min and above.

Tripmeter and tachometer modes
1. “SELECT” button
2. “RESET” button
Pushing the "SELECT" button switch-
es the display between the tripmeter
modes "TRIP 1" and "TRIP 2" in the
following order:
TRIP 1
6TRIP 2 6TRIP 1
When the fuel amount in the fuel tank
decreases to 6.7 L (1.77 US gal) (1.47
Imp.gal), the bottom segment of the
fuel meter will start flashing, and the
tripmeter display will automatically
change to the fuel reserve tripmeter
mode “F-TRIP” and start counting the
distance traveled from that point. In
that case, pushing the "SELECT" but-

ton switches the display between the
various tripmeter modes in the follow-
ing order:
F-TRIP
6TRIP 1 6TRIP 2 6F-TRIP
To reset a tripmeter, select it by push-
ing the "SELECT" button, and then
push the "RESET" button for at least
four seconds. If you do not reset the
fuel reserve tripmeter manually, it will
reset itself automatically and the dis-
play will return to the prior mode after
refueling and traveling 5 km (3 mi).

WARNING0
●Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the mo-
torcycle with excessively worn
tires decreases riding stability
and can lead to loss of control.
●The replacement of all wheel-
and brake-related parts, in-
cluding the tires, should be left
to a Yamaha dealer, who has
the necessary professional
knowledge and experience.
●It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube
very carefully and replace it as
soon as possible with a high-
quality product.

EAU21940
Spoke wheels
To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points regard-
ing the specified wheels.
●The wheel rims should be
checked for cracks, bends or
warpage, and the spokes for
looseness or damage before
each ride. If any damage is found,
have a Yamaha dealer replace the
wheel. Do not attempt even the
smallest repair to the wheel. A de-
formed or cracked wheel must be
replaced.
●The wheel should be balancedwhenever either the tire or wheel
has been changed or replaced.
An unbalanced wheel can result
in poor performance, adverse
handling characteristics, and a
shortened tire life.
●Ride at moderate speeds afterchanging a tire since the tire sur-
face must first be "broken in" for it
to develop its optimal characteris-
tics.
