Rear shock absorber (YFM70RSCN /
YFM70RCCN)
The shock absorber spring preload, rebound
damping force, and compression damping force
(fast and slow compression damping) can be ad-
justed.
WARNING
EWB02681
Suspension components become hot during
operation. Never touch the compression
damping force adjusting bolt and screw, the
rebound damping force adjusting screw or the
oil reservoir with your bare hand or skin until
the suspension components have cooled.
Notes on adjusting the suspension
A special wrench can be obtained at a Yamaha
dealer to make the spring preload adjustment.
When adjusting the damping force settings, turn
the adjuster in direction (a) until it stops, and
then count the turns or clicks in direction (b).
Although a damping force adjuster may turn or
click beyond the stated minimum settings, such
adjustments are ineffective and may damage
the suspension.
NOTICE
ECB00091
Never turn an adjusting mechanism beyond
the minimum and maximum settings.
Spring preload
1. Elevate the vehicle and place a suitable stand
under the frame.
2. Loosen the locknut.
3. Turn the spring preload adjusting nut in direc-
tion (a) to increase the spring preload and
thereby harden the suspension. Turn in direc-
tion (b) to decrease the spring preload and
thereby soften the suspension.
