impact on the handling, braking,
performance and safety characteris-
tics of your motorcycle, you should
keep the following precautions in
mind. l
NEVER OVERLOAD THE
MOTORCYCLE! Operation of an
overloaded motorcycle may re-
sult in tire damage, loss of con-
trol, or severe injury. Make surethat the total weight of rider,
passenger, cargo, and accesso-
ries does not exceed the speci-
fied maximum load for the
vehicle.
l
Do not carry along loosely
packed items, which can shift
during a ride.
l
Securely pack the heaviest
items close to the center of the
motorcycle and distribute the
weight evenly on both sides.
l
Adjust the suspension and tire
air pressure with regard to the
load.
l
Check the tire condition and air
pressure before each ride.

high-speed tires. Note the following
points in order to make the most ef-
ficient use of these tires.l
Use only the specified replace-
ment tires. Other tires may run

high speeds.
l
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 conserva-
tively for approximately 100 km
after installing a new tire.
