PIAGGIO Aprilia Tuono V4 1100 RR Manual page 98

The front suspension consists of a hydraulic fork connected to the headstock by
means of two plates.
To adjust the settings for this vehicle, each fork is equipped with an upper adjustment
screw (1) to set the rebound damping; an upper nut (3) to adjust the spring preloading
and a lower adjustment screw (2) to modify the compression damping.
IN ORDER TO AVOID DAMAGES DO NOT FORCE THE SET SCREWS TO TURN

BEYOND THE END OF THE STROKE ON BOTH SIDES. SET THE SAME SPRING
PRE-LOAD AND HYDRAULIC DAMPING SETTING FOR BOTH STANCHIONS:
RIDING THE VEHICLE WITH DIFFERENT SETTINGS FOR THE TWO STAN-
CHIONS REDUCES STABILITY. WHEN SPRING PRE-LOAD IS INCREASED, RE-
BOUND DAMPING MUST ALSO BE INCREASED TO PREVENT EXCESSIVE
SUSPENSION KICKBACK WHEN RIDING.

The standard front fork setting is adjusted to suit most high and low speed riding con-
ditions, whether the vehicle is partially or fully loaded.
However, the setting can be modified for specific needs according to vehicle use.
RACING TRACK SETTINGS MUST BE DONE ONLY FOR OFFICIAL COMPETI-
TIONS OR SPORTS EVENTS WHICH ARE, IN ALL CASES, AWAY FROM NOR-
MAL ROAD TRAFFIC AND WITH THE AUTHORISATION OF THE RELEVANT
