Brake fluid leakage (front brake)
Check to see if any brake fluid is leaking out of the
hose, joint or brake fluid reservoir of the front
brake. Apply the brake firmly for one minute. If the
lever moves slowly inward, there may be a leak in
the brake system. If there is any leakage, the brake
system should be checked by a Yamaha dealer.
Brake operation
Test the brakes at slow speed after starting out to
make sure they are working properly. If the brakes
do not provide proper braking performance,
check the brake pads and friction plates for wear.
(See page 9-42.)

Tires
Check and adjust the tire pressure before each
ride. Check tires for wear and damage.
Tire pressure
A low-pressure tire gauge is included as standard
equipment. Make two measurements of the tire
pressure and use the second reading. Dust or dirt
in the gauge could cause the first reading to be in-
correct.
Tire pressure must be checked and set when the
tires are cold. The tire pressure should be the
same on both sides, and must be adjusted ac-
cording to vehicle loading conditions. Set the tire
pressure as specified below.
WARNING! Opera-
tion of this vehicle with improper tire pressure
may cause severe injury or death from loss of
1. Low-pressure tire gauge
2. Tire air valve
