Rear suspension setting
The rear suspension setting should be made
depending on the rider’s feeling of an actual run
and the circuit conditions.
The rear suspension setting includes the follow-
ing two factors:
1. Setting of spring preload
9Change the set length of the spring.
9Change the spring.
2. Setting of damping force
9Change the rebound damping.
9Change the compression damping.

La registrazione della sospensione
posteriore dovrebbe essere effettuata in
base alla sensazione che il guidatore ha
di una corsa effettiva e alle condizioni
del circuito.
La registrazione della sospensione poste-
riore comprende i seguenti due fattori:
1. Registrazione del precarico della
molla
9Cambiare la lunghezza registra-
ta della molla.
9Cambiare la molla.
2. Registrazione della forza di smor-
zamento

Scelta della lunghezza registrata
1. Collocare sotto il motore un sup-
porto o un blocco per rialzare dal
suolo la parte superiore e misurare
la lunghezza afra il centro
dell’asse della ruota posteriore e il
bullone di tenuta del parafango
posteriore.

2. Remove the stand or block from the engine
and with a rider astride the seat, measure
the sunken length bbetween the rear wheel
axle center and the rear fender holding bolt.
3. Loosen the locknut 1and make adjustment
by turning the spring adjuster 2to achieve
the standard figure from the subtraction of
the length bfrom the length a.
Standard figure:
90~100 mm (3.5~3.9 in)
NOTE:
9If the machine is new and after it is broken in,
the same set length of the spring may change
because of the initial fatigue, etc. of the spring.
Therefore, be sure to make re-evaluation.
9If the standard figure cannot be achieved by
adjusting the spring adjuster and changing the
spring set length, replace the spring with an
optional one and make re-adjustment.

HINWEIS:
9Wenn eine neue Maschine eingefah-
ren worden ist, kann es sein, dass
die Einstellänge der Feder sich
ändert, aufgrund von Faktoren wie
Ermüdung der Feder etc. Es wird
darum empfohlen, nach dem Einfah-
ren die Einstellung zu überprüfen.
9Wenn der Standardwert durch Ein-
stellen des Federeinstellers und
Ändern der Federlänge nicht erreicht
werden kann, muss die Feder durch
eine Austauschfeder ersetzt und die
Einstellung neu vorgenommen wer-
den.
N.B.:
9Le ressort peut s’allonger au fur et à
mesure de la période de rodage. Il est
donc important de corriger les
réglages régulièrement.
9Si la valeur standard ne peut être obte-
nue à l’aide du dispositif de réglage et
en ajustant la longueur du ressort,
remplacer le ressort avec un ressort en
option et effectuer un nouveau régla-
ge.
NOTA:
9Se il veicolo è nuovo e dopo il rodag-
gio, la stessa lunghezza registrata
della molla può variare a causa della
fatica iniziale, ecc. della molla. Per-
tanto, assicurarsi di effettuare una
rivalutazione.
9Se non è possibile ottenere la cifra
normale regolando il regolatore della
molla e cambiando la lunghezza regi-
strata della molla, sostituire la molla
con una opzionale ed effettuare la ri-
regolazione.
