Tire inspection
1. Tire tread depth
2. Tire sidewall
The tires must be checked before
each ride. If the center tread depth
reaches the specified limit, if the tire
has a nail or glass fragments in it, or if
the sidewall is cracked, have a Yama-
ha dealer replace the tire immediately.
TIP
The tire tread depth limits may differ
from country to country. Always
comply with the local regulations.
Tire information
This motorcycle is equipped with
tubeless tires, tire air valves and cast
wheels.
EWA10461
The front and rear tires should be of
the same make and design, other-
wise the handling characteristics of
the vehicle may be different, which
could lead to an accident.
After extensive tests, only the tires lis-
ted below have been approved for
this model by Yamaha Motor Co., Ltd.
EWA10471
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
vehicle with excessively worn
tires decreases riding stability
and can lead to loss of control.
The replacement of all wheel
and brake-related parts, inclu-
ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience to do so.
Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken
in” for it to develop its optimal
characteristics.

Troubleshooting
Although Yamaha motorcycles recei-
ve a thorough inspection before ship-
ment from the factory, trouble may
occur during operation. Any problem
in the fuel, compression, or ignition
systems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your motorcy-
cle require any repair, take it to a
Yamaha dealer, whose skilled techni-
cians have the necessary tools, expe-
rience, and know-how to service the
motorcycle properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
EWA15141
When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in the
area, including pilot lights from
water heaters or furnaces. Gasoli-
ne or gasoline vapors can ignite or
explode, causing severe injury or
property damage.
