9.1.1 DESCRIPTION
The anti-lock brake system prevents wheel lockout in emer-
gency braking, thereby ensuring greater stability under braking
as compared to conventional braking systems. Under particu-
lar conditions, operating the brake may lead to wheel lockout
and loss of traction, which makes it very difficult to maintain
steering control. A position sensor (1)
≈ reads ∆ a phonic wheel
(2) mounted to the vehicle wheel to determine whether the
wheel is rolling or is locked. A control unit (3) adjusts the pres-
sure inside the brake circuit based on sensor signals.
CAUTION
When ABS is working, the rider will feel a
vibration on the brake lever.
CAUTION
Anti-lock brakes cannot avoid a fall when braking in a
bend. Emergency braking with the vehicle leaned over,
with the handlebar turned, when riding on uneven or
slippery surfaces or anyway in a poor grip situation will
make the vehicle unstable and difficult to control. Ride
carefully, apply the brakes gradually and be ready for the
unexpected. Remember that your ABS cannot defy the
laws of physics a vehicle braking in a bend is subject to.
When the sensors (1) detect a significant difference in
the speed of the front and rear wheel (as in a wheelie, for
instance), the ABS may read this as a dangerous condi-
tion. When this is the case, one of the following things
may happen:
- The ABS activates and releases pressure from the cal-
liper until the affected wheel regains the same speed
as the other wheel. During that instant, the rider has no
control over brake pressure.
- If speed difference persists, the system may see this
as a fault and disable ABS. The brake then operates
like a conventional brake.
When the engine is started, the light (6) comes on and
should go out after about 3 seconds. If the light stays on,
it means that a malfunction has been detected and the
ABS is switched off.
Riding with the ABS on
The light (6) stays off.
In the event of a fault, the light comes on steady to alert the
rider. The ABS is switched off automatically.
Riding with the ABS off
The light (6) will be flashing.
How to disable the ABS.
To disable the ABS with the engine running and the motor-
cycle at standstill, wait for the light to go out and press the
switch (7). Hold down the switch until the light begins to flash
and then release it before the light can flash 5 times. To ena-
ble the ABS, stop the motorcycle and the engine and repeat
the process.

ABS operation is based on the speed of the front and rear
wheel detected by the corresponding sensors. Be careful to
avoid damage to the phonic wheels (2) when servicing the
vehicle wheels or adjacent components. A damaged phonic
wheel may impair correct ABS operation.
