Braking system
D - Pressure restored: by opening the inlet valve (10-12) momentarily, the pressure of the callipers
(8-9) is increased until maximum deceleration is reached. Then, the system gives the control over the
braking back to the rider.
E - If the wheel does not reach complete grip, the system continues operating as before until complete
grip is obtained or until the vehicle stops. An error can be detected if the duration of the pressure
reduction phase exceeds the pre-set time limit.
ABS SYSTEM DESCRIPTION
The ABS system is a device to avoid wheels locking in case of emergency braking, increasing vehicle
braking stability when compared to a traditional braking system.
The ABS system enhances control over the vehicle, taking into consideration never to exceed the
physical limits of vehicle grip on the road. The rider is fully responsible for riding at a suitable speed
based on weather and road conditions, always leaving an appropriate safety margin. Under no circum-
stances can the ABS system compensate for the rider's misjudgement or improper use of brakes.
Sometimes when the brake is operated, the tyre locks with a consequent loss of grip, which makes it
difficult to control the vehicle.
A position sensor (3) on the tone wheel (2), forming an integral unit with the vehicle wheel, "reads" the
status of the vehicle wheel spotting any possible lock.
A control unit (1) signals this out and adjusts the pressure in the braking circuit accordingly.
CAUTION
WHEN THE ABS STARTS WORKING, A PULSING IS FELT ON THE BRAKE LEVER.
THE WHEEL ANTILOCK SYSTEM DOES NOT PREVENT FALLS WHILE ON A BEND. AN EMER-
GENCY BRAKING WITH THE VEHICLE INCLINED, HANDLE BAR TURNED, ON UNEVEN OR
SLIPPERY ROADS, OR WITH POOR GRIP CREATES LACK OF STABILITY DIFFICULT TO HAN-
DLE. THEREFORE, RIDE CAREFULLY AND SENSIBLY AND ALWAYS BRAKE GRADUALLY.
BRAKING WHILE TURNING A CORNER IS SUBJECT TO LAWS OF PHYSICS WHICH NOT EVEN
ABS CAN ELIMINATE.
When sensors (3) detect a significant speed difference between the rear and the front wheels (for
example, when rearing up on the back wheel), the ABS system could take this as a dangerous situation.
In this case, 2 things may occur:
