EXUP system
This motorcycle is equipped with
Yamaha’s EXUP (EXhaust Ultimate
Power valve) system. This system
boosts engine power by means of a
valve that regulates the diameter of the
exhaust pipe. The EXUP system valve
is constantly adjusted in accordance
with the engine speed by a computer-
controlled servomotor.
EC000027
CAUTION:
_
●
The EXUP system has been set
and extensively tested at the
Yamaha factory. Changing
these settings without sufficient
technical knowledge may result
in poor performance of or dam-
age to the engine.
●
If the EXUP system does not op-
erate, have a Yamaha dealer
check it.

Sidestand
The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
motorcycle upright.
NOTE:
_
The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation of
the ignition circuit cut-off system.)

EW000044
WARNING
_
The motorcycle must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up), oth-
erwise the sidestand could contact
the ground and distract the opera-
tor, resulting in a possible loss of
control. Yamaha’s ignition circuit
cut-off system has been designed to
assist the operator in fulfilling the
responsibility of raising the side-
stand before starting off. Therefore,
check this system regularly as de-
scribed below and have a Yamaha
dealer repair it if it does not function
properly.
