GIVE SAFETY THE RIGHT OF WAY
GENERAL INFORMATION
GIVE SAFETY THE RIGHT OF WAY
Motorcycles are fascinating vehicles, which can give you an unsurpassed feeling of power and freedom. Howev-
er, they also impose certain limits, which you must accept; even the best motorcycle does not ignore the laws of
physics.
Regular care and maintenance are essential for preserving your motorcycle’s value and operating condition.
Moreover, what is true for the motorcycle is also true for the rider: good performance depends on being in good
shape. Riding under the influence of medication, drugs and alcohol is, of course, out of the question. Motorcycle
riders – more than car drivers – must always be at their mental and physical best. Under the influence of even
small amounts of alcohol, there is a tendency to take dangerous risks.
Protective clothing is as essential for the motorcycle rider as seat belts are for car drivers and passengers. Al-
ways wear a complete motorcycle suit (whether made of leather or tear-resistant synthetic materials with protec-
tors), sturdy boots, motorcycle gloves and a properly fitting helmet. Optimum protective wear, however, should
not encourage carelessness. Though full-coverage helmets and suits, in particular, create an illusion of total safe-
ty and protection, motorcyclists will always be vulnerable. Riders who lack critical self-control run the risk of going
too fast and are apt to take chances. This is even more dangerous in wet weather. The good motorcyclist rides
safely, predictably and defensively – avoiding all dangers, including those caused by others.
Enjoy your ride!

OPERATION AND IMPORTANT RIDING POINTS/
INCLUDED ACCESSORIES
EAU01128
Engine break-in
There is never a more important period
in the life of your motorcycle than the
period between zero and 1,600 km. For
this reason we ask that you carefully
read the following material. Because
the engine is brand new, you must not
put an excessive load on it for the first
1,600 km. The various parts in the en-
gine wear and polish themselves to the
correct operating clearances. During
this period, prolonged full throttle oper-
ation, or any condition which might re-
sult in excessive heating of the engine,
must be avoided.
EAU013290 ~ 1,000 km
Avoid operation above 5,500 r/min.
1,000 ~ 1,600 km
Avoid cruising speeds in excess of
7,000 r/min.
EC000052
CAUTION:
After 1,000 km of operation, be sure
to replace the engine oil and oil fil-
ter.
1,600 km and beyond
Proceed with normal riding.
EC000053
CAUTION:
lNever let engine speeds enter
the red zone.
lIf any engine trouble should oc-
cur during the break-in period,
consult a Yamaha dealer imme-
diately.
EAU00460
Parking
When parking the motorcycle, stop the
engine and remove the ignition key.
EW000058
WARNING
The exhaust system is hot. Park the
motorcycle in a place where pedes-
trians or children are not likely to
touch the motorcycle. Do not park
the motorcycle on a slope or soft
ground; the motorcycle may over-
turn.
INCLUDED ACCESSORIES
EAU01575
Tool kit
The tools provided in the owner’s tool
kit are to assist you in the performance
of periodic maintenance. However,
some other tools such as a torque
wrench are also necessary to perform
the maintenance correctly.
The service information included in this
manual is intended to provide you, the
owner, with the necessary information
for completing some of your own pre-
ventive maintenance and minor re-
pairs.
NOTE:
If you do not have necessary tools re-
quired during a service operation, take
your motorcycle to a Yamaha dealer
for service.
EW000063
WARNING
Modifications to this motorcycle not
approved by Yamaha may cause
loss of performance, and render it
unsafe for use. Consult a Yamaha
