ADJUSTING THE FRONT DISC BRAKE
1. Adjust:
Brake lever position
(distance “a” from the throttle grip to the
brake lever)
TIP
While pushing the brake lever forward, turn
the adjusting dial “1” until the brake lever is in

WARNING
EWA13060
After adjusting the brake lever position,
make sure the pin on the brake lever
holder is firmly inserted in the hole in the
adjusting dial.
A soft or spongy feeling in the brake lever
can indicate the presence of air in the
brake system. Before the vehicle is oper-
ated, the air must be removed by bleeding
the brake system. Air in the brake system
will considerably reduce in loss of control
and possibly an accident. Therefore,
check and if necessary, bleed the brake
system.
