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 level.
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 level and characteristics of fork oil
Damping characteristic near the final stroke can
be changed by changing the fork oil amount.

Adjust the oil level in 5 mm (0.2 in) incre-
ments or decrements. Too low oil level
causes the front fork to produce a noise at
full rebound or the rider to feel some pres-
sure on his hands or body. Alternatively,
too high oil level will develop unexpectedly
early oil lock with the consequent shorter
front fork travel and deteriorated perfor-
mance an characteristics. Therefore, adjust
the front fork within the specified range.
