EINSTELLUNG
Choix de la longueur de ressort
1. Placer un support ou un bloc sous le moteur
pour surélever la roue arrière et mesurer la lon-
gueur a entre le centre de l’axe de roue arrière
et le boulon de fixation du garde-boue arrière.
2. Retirer le support ou le bloc et mesurer, avec
une personne assise correctement sur la selle, la
longueur b entre le centre de l’axe de roue
arrière et le boulon de fixation du garde-boue
arrière.
3. Desserrer le contre-écrou 1 et effectuer le
réglage en tournant le dispositif de réglage 2
de manière à atteindre la valeur standard, obte-
nue en soustrayant la longueur b de la lon-
gueur a.
Valeur standard:
75 à 85 mm (3,0 à 3,3 in)
N.B.:

Si la moto est nouvelle et après qu’elle a été
rodée, la longueur du ressort peut changer en rai-
son de la fatigue initiale, etc., du ressort. Il est
donc important de corriger les réglages régulière-
ment.

S’il est impossible d’atteindre la valeur standard 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 réglage.Federeinbaulänge wählen
1. Das Motorrad am Motor aufbocken, um
das Hinterrad anzuheben, und den
Abstand a zwischen der Hinterachsmitte
und der Hinterrad-Abdeckungs- Schraube
messen.
2. Das Motor herablassen und bei aufsitzen-
dem Fahrer den Abstand b zwischen der
Hinterachsmitte und der Hinterrad-Abdek-
kungs-Schraube messen.
3. Die Sicherungsmutter 1 lockern und die
Einstellmutter 2 verdrehen, um die Stan-
dard-Federeinbaulänge durch Subtraktion
der Länge b von der Länge a zu erhal-
ten.
Standardwert
75–85 mm
HINWEIS:

Bei einer neuen Maschine kann sich die
Federeinbaulänge z.B. durch die Anfangser-
müdung der Feder beim Einfahren verän-
dern. Die Einstellung muß deshalb nach dem
Einfahren überprüft werden.

Kann die Standardlänge nicht durch Einstel-
lung erreicht werden, muß die Feder ersetzt
werden und die Einstellung ist neu vorzuneh-
men.
