Adjusting The Shock Absorber Assembly - Yamaha YZF-R1 Owner's Manual

TIP
Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in
production, the actual number of clicks
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify the
specifications as necessary.
INSTRUMENT AND CONTROL FUNCTIONS
Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with a spring preload adjust-
ing bolt, a rebound damping force ad-
justing screw, a compression damping
force adjusting bolt (for fast compres-
sion damping) and a compression
damping force adjusting bolt (for slow
compression damping).
NOTICE
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
Spring preload
Adjust the spring preload by turning the
spring preload adjusting bolt and align-
ing the match mark with the "
on the shock absorber assembly.
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt in direction (a). To de-
crease the spring preload and thereby
soften the suspension, turn the adjust-
ing bolt in direction (b).
