CHASSIS
ADJUSTING THE FRONT BRAKE
1. Adjust:
• Brake lever position
(distance abetween the brake lever and
the handlebar grip)
a. Turn the adjusting dial 1while holding the
lever pushed away from the handlebar grip
NOTE:
Align the setting on the adjusting dial with the
arrow mark 2
WARNING
After adjusting the brake lever position, make
sure the pin on the brake lever holder is firm-
ly inserted in the hole in the adjusting dial.
WARNING
A soft or spongy feeling in the brake lever can
indicate the presence of air in the brake sys-
tem. Before the vehicle is operated, the air
must be removed by bleeding the brake sys-
tem. Air in the brake system will considerably
reduce braking performance and could result
in loss of control and possibly an accident.
Therefore, inspect and, if necessary, bleed the
brake system. After adjusting the brake lever
free play, make sure that there is no brake
drag.

BRAKE CIRCUIT BLEEDING
WARNING
If the brake lever or brake pedal has a soft or
slack feel, this means that there is air in the
brake system. It should be bled away before
using the motorcycle. Air in the system seri-
ously affects the effectiveness of braking and
may cause loss of control of the motorcycle.
In all cases, bleed the brake system if:
•The system has been disassembled.
•A brake hose has been loosened or
removed.
•The brake fluid in the tank is at a very low
level.
•Brake operation is faulty.
Air bleeding procedures:
a. Top up the level of the fluid in the tank to max-
imum.
b. Install the diaphragm. Be careful not to spill
fluid or let it overflow from the tank.
c. Connect the clear plastic hose (1) to the
caliper bleeder screw.
[A] Front
[B] Rear
d. Place the other end of the hose in a container.
e. Slowly pull the brake lever or press the brake
pedal several times.
f. Pull the brake lever right in or press the pedal
right down and hold in position.
g. Loosen the bleeder screw and allow the lever
or pedal to travel slowly towards its limit.
h. Tighten the bleeder screw when the lever or
pedal limit has been reached, then release the
lever or pedal.
Bleeder screw:
14 Nm (1.4 mkg)
i. Repeat operations (e) to (h) until all the air
bubbles have disappeared from the clear
plastic hose (1).

brake circuit.
See section “AIR BLEEDING (HYDRAULIC
BRAKE SYSTEM)” in CHAPTER 3.
Installation procedure:
•Connect the hose (1) firmly to the caliper
bleeder screw (2). Place the other end of the
hose in an open container.
•Loosen the caliper bleeder screw and push
the pistons into the caliper with your finger.
•Retighten the bleeder screw (2).
Caliper bleeder screw: 14 Nm (1.4 mkg)

Brake fluid may deteriorate painted surfaces
or plastic parts. Always clean up spilled fluid
immediately.
CAUTION:
WARNING
•Use only designated quality brake fluid.
Otherwise, the rubber seals may deterio-
rate, causing leakage and poor brake per-
formance.
•Refill with the same type of brake fluid:
mixing fluids may result in a harmful chem-
ical reaction and lead to poor perform-
ance.
•Be careful that water does not enter the
significantly lower the boiling point of the
fluid may result in vapor lock.
