ANTI-LOCK BRAKE SYSTEM (FJR1300A)

Cautions for operation

ABS warning light:
• When the main switch is set to "ON", the ABS warning light comes on for 2 seconds, then goes
off.
• If the ABS warning light comes on while riding, stop the motorcycle, and then set the main switch
to "OFF", then set the main switch to "ON". The ABS operation is normal if the ABS warning light
comes on for 2 seconds, then off.
• If the rear wheel is raced with the motorcycle on the centerstand, the ABS warning light may
flash or come on. If this occurs, set the main switch to "OFF," then back to "ON". The ABS oper-
ation is normal if the ABS warning light comes on for 2 seconds, then goes off.
• The ABS operation is normal if the ABS warning light flashes.
• Even if the ABS warning light remains on and does not go off or if it comes on after riding, con-
ventional braking performance of the motorcycle is maintained.

ABS function:

• A brake system in which the hydraulic control has been performed by the ABS alerts a rider that
the wheels had a tendency to lock by generating a reaction-force pulsating action in the brake
lever or brake pedal. When the ABS is activated, the grip between the road surface and tires is
close to the limit. The ABS cannot prevent wheel lock* on slippery surfaces such as ice, when it
is caused by engine braking, even if the ABS is activated.
• The ABS is not designed to shorten the braking distance or improve the cornering performance.
• Depending on the road conditions, the braking distance may be longer compared to that of vehi-
cles not equipped with an ABS. Therefore, ride at a safe speed and keep a safe distance
between yourself and other vehicles.
• The braking of the motorcycle, even in the worst case, is principally executed when the motorcy-
cle is advancing straight ahead. During a turn, sudden braking is liable to cause a loss of traction
of the tires. Even motorcycles equipped with an ABS cannot be prevented from falling over if
braked suddenly.
• The ABS does not work when the main switch is set to "OFF". The conventional braking function
can be used.
* Wheel lock: A condition that occurs when the rotation of one or both of the wheels has stopped
but the motorcycle continues to travel.
