Adjusting The Front Fork - Yamaha MT-09 Owner's Manual

Adjusting the front fork

WARNING
Always adjust the spring preload
on both fork legs
otherwise poor handling and loss
of stability may result.
Each front fork leg is equipped with a
spring preload adjusting bolt, the right
front fork leg is equipped with a
rebound damping force adjusting
screw and the left front fork leg with a
compression damping force adjusting
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
direction (a). To decrease the spring
preload and thereby soften the
suspension, turn the adjusting bolt on
each fork leg in direction (b).

direction (a). To decrease the rebound
damping force and thereby soften the
rebound damping, turn the adjusting
screw in direction (b).
TIP
Be sure to perform this adjustment on
the right front fork leg.
