SAFETY INFORMATION
EAU10281
MOTORCYCLES ARE SINGLE
TRACK VEHICLES. THEIR SAFE USE
AND OPERATION ARE DEPENDENT
UPON THE USE OF PROPER RIDING
TECHNIQUES AS WELL AS THE EX-
PERTISE OF THE OPERATOR. EV-
ERY OPERATOR SHOULD KNOW
THE FOLLOWING REQUIREMENTS
BEFORE RIDING THIS MOTOR-
CYCLE.
HE OR SHE SHOULD:

OBTAIN THOROUGH INSTRUC-
TIONS FROM A COMPETENT
SOURCE ON ALL ASPECTS OF
MOTORCYCLE OPERATION.


OBSERVE THE WARNINGS AND
MAINTENANCE REQUIRE-
MENTS IN THE OWNER’S MAN-
UAL.


OBTAIN QUALIFIED TRAINING
IN SAFE AND PROPER RIDING
TECHNIQUES.


OBTAIN PROFESSIONAL TECH-
NICAL SERVICE AS INDICATED
BY THE OWNER’S MANUALAND/OR WHEN MADE NECES-
SARY BY MECHANICAL CONDI-
TIONS.
Safe riding


Always make pre-operation
checks. Careful checks may help
prevent an accident.


This motorcycle is designed to car-
ry the operator and a passenger.


The failure of motorists to detect
and recognize motorcycles in traf-
fic is the predominating cause of
automobile/motorcycle accidents.
Many accidents have been caused
by an automobile driver who did
not see the motorcycle. Making
yourself conspicuous appears to
be very effective in reducing the
chance of this type of accident.
Therefore:
Wear a brightly colored jacket.
Use extra caution when you are
approaching and passing
through intersections, since in-
tersections are the most likely
places for motorcycle accidents
to occur.Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.


Many accidents involve inexperi-
enced operators. In fact, many op-
erators who have been involved in
accidents do not even have a cur-
rent motorcycle license.
Make sure that you are qualified
and that you only lend your
motorcycle to other qualified op-
erators.
Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
We recommend that you prac-
tice riding your motorcycle
where there is no traffic until you
have become thoroughly famil-
iar with the motorcycle and all of
its controls.


Many accidents have been caused
by error of the motorcycle opera-
tor. A typical error made by the op-
erator is veering wide on a turn

sion damping force and thereby soften
the compression damping, turn the ad-
justing bolt in direction (b).
Compression damping force (for slow
compression damping)To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting bolt in
direction (a). To decrease the compres-
sion damping force and thereby soften
the compression damping, turn the ad-
justing bolt in direction (b).
NOTE:Although the total number of clicks or
turns of a damping force adjusting
mechanism may not exactly match the
specifications listed due to small differ-
ences in production, the actual number
of clicks or turns always represents the
entire adjustment range. To obtain a
precise adjustment, it would be advis-
able to check the number of clicks or
turns of each damping force adjusting
mechanism and to modify the specifi-cations as necessary.
WARNING
EWA10220
This shock absorber contains highly
pressurized nitrogen gas. For prop-
er handling, read and understandthe 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 dealerservice the shock absorber.

CAL LOCATION, AND INDIVIDUAL
USE, THE MAINTENANCE INTER-
VALS MAY NEED TO BE SHORT-
ENED.
