2.29.2 ADJUSTING THE FRONT FORK
The standard setting of the front fork is such as to satisfy
most driving conditions at low and high speed, either with
reduced load and full load.
However, it is also possible to adjust the setting accord-
ing to the intended use of the vehicle.
a
CAUTION
For the adjustment, always start from the most rigid
setting [complete clockwise rotation of the adjusters
(1-2)].
Do not rotate the adjusters (1-2) beyond their limit po-
sition, to avoid damaging the thread.
Use the notches (1-2) provided on the adjusters as ref-
erence marks for the adjustment of the hydraulic brak-
ing with compressed and extended shock absorber.
Give the adjusters (1-2) 1/8 turn at a time and turn the
adjusting nut (3) one notch at a time.
Test the vehicle repeatedly on the road, until obtaining
the optimal adjustment.
Set the same spring preload and hydraulic braking for
both rods: a different setting of the rods decreases the
stability of the vehicle while riding.
When the spring preload is increased, it is necessary
to increase also the hydraulic braking, in order to
avoid sudden jerks while riding.
