Adjusting The Rear Shock Absorber - APRILIA RSV MILLE - PART 3 1999 Manual

The rear suspension consists of a hydrau-
lic shock absorber - spring unit, which is
mounted to the frame with a uniball, and to
the swinging arm by means of a system of
levers.
The ride height of the rear of the vehicle
can be set using the spring preload adjust-
ing ring nut (3) and locking ring nut, (4).
The rear suspension can be tuned by ad-
justing the extension damping with a spring
adjuster (1), the damping on compression
can be adjusted by a knob (2).
ADJUSTING
THE REAR SHOCK ABSORBER
The rear shock absorber is set at the facto-
ry to satisfy most riding conditions, at either
low or high speed, and with either a light or
full load. However, it is possible to tune the
suspension to your preference by using the
above mentioned adjustments.
CAUTION
When adjusting the rear shock absorber,
always start from the stiffest position.
This is the fully clockwise position of the
extension damper adjusting screw (1)
and the compression damper knob (2).
Do not rotate the extension damper ad-
justment screw (1) beyond its limit, this
will damage the screw and destroy your
shock absorber.

use and maintenance RSV mille
Always make sure, when adjusting
screw (1), that it clicks in to an adjust-
ment notch, and is not at a position inter-
mediate between adjustment notches.
The distance between the top of the ad-
justment ring and the top of the threads
must not exceed 1.10 ± 0.20 in (28 ± 5
mm). Adjusting the nut further down on
the shock will compress the spring ex-
cessively, and result in an uneven
bumpy ride. Also, it will be impossible to
adequately adjust the extension damp-
ing using screw (1).
N
Loosen the locking ring nut (4) by means
of the appropriate spanner wrench.
N
Adjust the adjusting ring nut (3) (see fig-
ure).
N
If necessary, adjust the extension damp-
ing screw (1) (see table p. 85).
N
Once the ride height has been properly
adjusted, tighten the lock ring nut (4)
completely.
N
Slightly loosen the lock nut (5).
Rotate the adjuster (6) one turn at a time
so that the adjusting screw (1) faces out
to the left side of the vehicle.
N
Using the appropriate wrench, turn the
adjuster (6) (which adjusts the center to
center distance of the shock absorber
unit) (see table p. 85).
