REAR SUSPENSION INSPECTION
Inspect the rear suspension following the instruc-
tions on the scheduled maintenance table.

REAR SUSPENSION ADJUSTMENT
The rear suspension consists of a double-acting
shock absorber (compression/rebound damping),
with silent-block engine mount. Standard rear
shock absorber setting is adjusted to suit most
high and low speed riding conditions, both with re-
duced and full vehicle load. It is at any rate possi-
ble to insert personal settings, depending on
vehicle utilisation: operate on the ring nut to define
the ideal running settings (see table).
