CAUTION
Using other than original spare parts such
as brake pads and discs on ABS equipped vehicles may
impair braking efficiency and compromise safety. It is
important to check that both tyres are at the correct infla-
tion pressure. Both tyres must be at the same pressure.
The ABS may respond unpredictably when the vehicle is
used for sports riding. Turn off your ABS before any such
use.

9.1.2 COMPONENT MAINTENANCE

The vehicle is equipped with a two-channel ABS that
monitors both the front and rear wheel.
Check sensor gap at regular intervals, after each wheel
removal and after replacing a phonic wheel (2) or a wheel
sensor (1). Air gap should be the same at all positions of
the phonic wheel (through 360°). Measure air gap
between sensor (1) and phonic wheel (2) using a feeler
gauge at three locations spaced 120° apart. Correct rea-
dings must be within the following ranges:
Front 0,4 - 1,85 mm (0.016 – 0.073 in);
Rear 0,7 - 1,80 mm (0.028 – 0.071 in);
CAUTION
If measured gap is outside the allowed
range, change the sensor (1) and/or the phonic wheel (2)
and check again, making sure all measurements are
within the specified range.
CLEANING THE PHONIC WHEELS (2)
It is important to make sure the phonic wheels (2) are
clean at all times.
If not so, gently remove any dirt with a cloth or a wire
brush. Avoid using solvents or abrasive products. When
using an air line or a water cleaner, do not aim the nozzle
directly at the phonic wheel (2).
9.1.3 REPLACING THE FRONT WHEEL SENSOR
! Disconnect the connector (1) of the wheel sensor (3)
from the main wiring harness.
! Unscrew and remove the screw (2) and remove the
front wheel sensor (3).
CAUTION
On refitting, make sure the mating sur-
faces of sensor (3) and sensor housing are smooth and
clean. Always check the gap between sensor (3) and
phonic wheel, vedi 9.1.2 (COMPONENT MAINTE-
NANCE).
