EWA10220
This shock absorber contains highly
pressurized nitrogen gas. For prop-
er handling, read and understand
the following information before
handling the shock absorber. The
manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.
● Do not tamper with or attempt to
open the gas cylinder.
● Do not subject the shock ab-
sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.
● Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.
● Always have a Yamaha dealer
service the shock absorber. EAU15281
EXUP system
This model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine

lates the diameter of the exhaust pipe.
The EXUP system valve is constantly
adjusted in accordance with the engine
speed by a computer-controlled servo-
motor.
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 cannot be
heard when the main switch is
turned on, have a Yamaha deal-
er check it.
