Adjusting The Front Fork - Yamaha FJR13AD(C) Owner's Manual

INSTRUMENT AND CONTROL FUNCTIONS

Adjusting the front fork

WARNING
Always adjust the spring preload on
both fork legs equally, otherwise
poor handling and loss of stability
may result.
Each front fork leg is equipped with a
spring preload adjusting bolt. The right
4
front fork leg is equipped with a re-
bound damping force adjusting knob
and compression damping force ad-
justing screw.
NOTICE
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt on each fork leg in di-
rection (a). To decrease the spring pre-
load and thereby
suspension, turn the adjusting bolt on
each fork leg in direction (b).

The spring preload setting is deter-
mined by measuring distance A, shown
in the illustration. The shorter distance
A is, the higher the spring preload; the

longer distance A is, the lower the
spring preload.

Rebound damping force
The rebound damping force is adjusted
on the right front fork leg only.
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting knob in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting knob in di-
rection (b).
