SETTING
EC72A001
Setting of spring after replacement
As the front fork setting can be easily affected by
rear suspension, take care so that the machine
front and rear are balanced (in position, etc.)
when setting the front fork.
1. Use of soft spring
Generally a soft spring gives a soft riding
feeling. Rebound damping tends to become
stronger and the front fork may sink deeply
over a series of gaps.
To set a soft spring:
9 Change the rebound damping.
Turn out one or two clicks.
9 Change the compression damping.
Turn in one or two clicks.
2. Use of stiff spring
Generally a stiff spring gives a stiff riding
feeling. Rebound damping tends to become
weaker, resulting in lack of a sense of con-
tact with the road surface or in a vibrating
handlebar.
To set a stiff spring:
9 Change the rebound damping.
Turn in one or two clicks.
9 Change the compression damping.
Turn out one or two clicks.
