characteristics of the motorcy-
cle may be different, which
could lead to an accident.
Always make sure that the valve
caps are securely installed to
prevent air pressure leakage.
Use only the tire valves and
valve cores listed below toavoid tire deflation during a ride.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha.
WARNING
EWA10601
This motorcycle is fitted with su-
per-high-speed tires. Note the fol-
lowing points in order to make the
most efficient use of these tires.
Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds.
Brand-new tires can have a rela-
tively poor grip on certain road
surfaces until they have been
“broken in”. Therefore, it is ad-
visable before doing any
high-speed riding to ride con-
servatively for approximately
100 km (60 mi) after installing a
new tire.
The tires must be warmed up
before a high-speed run.
Always adjust the tire air pres-
sure according to the operatingconditions.
EAU21963
Cast wheelsTo maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
The wheel rims should be checked
for cracks, bends, warpage or oth-
er damage before each ride. If any
damage is found, have a Yamaha
dealer replace the wheel. Do not
attempt even the smallest repair to
the wheel. A deformed or cracked
wheel must be replaced.
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.

turn the adjusting bolt in direction (b).
TIPIf the specified clutch lever free play
cannot be obtained as describedabove, proceed as follows. 1. Fully turn the adjusting bolt at the clutch lever in direction (a) to loos-
en the clutch cable.
2. Loosen the locknut further down the clutch cable.

Checking the brake lever free
playThere should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.

A soft or spongy feeling in the brake
lever can indicate the presence of air
in the hydraulic system. If there is air
in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the vehicle. Air in the
hydraulic system will diminish the
braking performance, which may re-

Rear brake pads
Each rear brake pad is provided with a
wear indicator groove, which allows
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator groove. If a brake
pad has worn to the point that the wear
indicator groove almost appears, have
a Yamaha dealer replace the brake
pads as a set.

Improper maintenance can result in
loss of braking ability. Observe
these precautions:
Insufficient brake fluid may al-

tem, reducing braking
performance.
Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.
