Safety information
EAU84510
Be a Responsible Owner
As the vehicle’s owner, you are re-
sponsible for the safe and proper oper-
ation of your motorcycle.
This is a leaning multi-wheel motorcy-
cle.
The safe use and operation of this mo-
torcycle is dependent upon the use of
proper riding techniques as well as the
expertise of the operator. Every opera-
tor should know the following require-
ments before riding this motorcycle.
He or she should:  Obtain thorough instructions from
a competent source on all aspects
of motorcycle operation.
 Observe the warnings and mainte-
nance requirements in this Own-
er’s Manual.
 Obtain qualified training in safe
and proper riding techniques.
 Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and when made neces-
sary by mechanical conditions. 
Never operate a motorcycle with-
out proper training or instruction.
Take a training course. Beginners
should receive training from a cer-
tified instructor. Contact an autho-
rized motorcycle dealer to find out
about the training courses nearest
you.
Safe Ri din g
Perform the pre-operation checks
each time you use the vehicle to make
sure it is in safe operating condition.
Failure to inspect or maintain the vehi-
cle properly increases the possibility of
an accident or equipment damage.
See page 4-1 for a list of pre-operation
checks.  This motorcycle is designed to
carry the operator and a passen-
ger.
 The failure of motorists to detect
and recognize motorcycles in traf-
fic is the predominating cause of
automobile-and-motorcycle acci-
dents. Many accidents have been
caused by an automobile driver
who did not see the motorcycle.
Making yourself conspicuous ap- pears to be very effective in reduc-
ing 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.
• Never maintain a motorcycle without proper knowledge.
Contact an authorized motorcy-
cle dealer to inform you on ba-
sic motorcycle maintenance.
Certain maintenance can only
be carried out by certified staff.UBD5E0E0.book Page 1 Wednesday, April 25, 2018 2:23 PM

Immo bilizer system in dicator
li g ht “ ”
When the key is turned to “OFF” and
30 seconds have passed, the indicator
light will flash steadily to indicate the
immobilizer system is enabled. After 24
hours have passed, the indicator light
will stop flashing, however the immobi-
lizer system is still enabled.
The electrical circuit of the indicator
light can be checked by turning the key
to “ON”. The indicator light should
come on for a few seconds, and then
go off.
If the indicator light does not come on
initially when the key is turned to “ON”,
if the indicator light remains on, or if the
indicator light flashes in a pattern (if a
problem is detected in the immobilizer
system, the immobilizer system indica-
tor light will flash in a pattern), have a
Yamaha dealer check the vehicle.
TIPIf the immobilizer system indicator light
flashes in the pattern, slowly 5 times
then quickly 2 times, this could be
caused by transponder interference. If
this occurs, try the following. 1. Make sure there are no other im- mobilizer keys close to the main
switch. Other immobilizer system
keys may cause signal interfer-
ence and prevent the engine from
starting.
2. Use the code re-registering key to start the engine.
3. If the engine starts, turn it off, and try starting the engine with the
standard keys.
4. If one or both of the standard keys do not start the engine, take the
vehicle and all 3 keys to a Yamaha
dealer to have the standard keys
re-registered.
