SETTING
EC722011
Front fork setting
The front fork setting should be made depending
on the rider's feeling of an actual run and the cir-
cuit conditions.
The front fork setting includes the following three
factors:
1. Setting of air spring characteristics
9 Change the fork oil amount.
2. Setting of spring preload
9 Change the spring.
9 Install the adjustment washer.
3. Setting of damping force
9 Change the compression damping.
9 Change the rebound damping.
The spring acts on the load and the damp-
ing force acts on the cushion travel speed.

Change in amount and characteristics of fork
oil
Damping characteristic near the final stroke can
be changed by changing the fork oil amount.
cC
Adjust the oil amount in 5 cm
0.2 US oz) increments or decrements. Too
small oil amount causes the front fork to
produce a noise at full rebound or the rider
to feel some pressure on his hands or
body. Alternatively, too large oil amount
will develop unexpectedly early oil lock
with the consequent shorter front fork trav-
el and deteriorated performance and char-
acteristics. Therefore, adjust the front fork
within the specified range.
