most efficient use of these tires.
G
Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super

G 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
high-speed riding to ride con-
servatively for approximately
4
100 km (60 mi) after installing a
new tire.

Cast wheels

To maximize the performance, durabil-
ity, and safe operation of your motorcy-
cle, note the following points regarding
the specified wheels.
G
The wheel rims should be checked
for cracks, bends, warpage or
damage before each ride. If any
damage is found, have a Yamaha
doing any
dealer replace the wheel. Do not
attempt even the smallest repair to
the wheel. A deformed or cracked
wheel must be replaced.
G 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.
G Ride at moderate speeds after
changing a tire since the tire sur-
face must first be "broken in" for it
to develop its optimal characteris-
tics.
G
After repairing or replacing a tire,
tighten the valve stem nut and
locknut to the specified torques.
