Adjusting The Shock Absorber Assembly - Yamaha XT250Z Owner's Manual

Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with a spring preload adjust-
ing ring.
It is recommended to have a Yamaha
dealer adjust the spring preload. How-
ever, if you choose to make this adjust-
ment yourself, obtain a special wrench
at a Yamaha dealer.
NOTICE
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
1. Loosen the locknut.
2. To increase the spring preload and
thereby harden the suspension,
turn the adjusting ring in direction
(a). To decrease the spring pre-
load and thereby soften the sus-
pension, turn the adjusting ring in
direction (b).
The spring preload setting is deter-
mined by measuring distance A,
shown in the illustration. The short-
er the distance A is, the higher the
