Adjusting The Shock Absorber Assembly - Yamaha 2009 YZF-R1Z Owner's Manual

pression damping force and thereby
soften the compression damping, turn
the adjusting screw in direction (b).
TIP
Be sure to perform this adjustment on
the left front fork leg.
Compression damping setting:
Minimum (soft):
25 click(s) in direction (b)*
Standard:
20 click(s) in direction (b)*
Maximum (hard):
1 click(s) in direction (b)*
* With the adjusting screw fully turned
in direction (a)
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.
