ADJUSTING THE SPRING
PRELOAD
The spring preload is adjusted by in-
stalling the adjustment washer "1" be-
tween the fork spring "2" and damper
rod "3".
Do not install three or more adjust-
ment washers for each front fork.
Always adjust each front fork to
the same setting. Uneven adjust-
ment can cause poor handling and
loss of stability.

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
• Change the rebound damping.
Turn out one or two clicks.
• Change the compression damp-
ing.
Turn in one or two clicks.
Generally a soft spring gives a soft
riding feeling. Rebound damping
tends to become stronger and the
front fork may sink deeply over a se-
ries of gaps.
2. Use of stiff spring
• Change the rebound damping.
Turn in one or two clicks.
• Change the compression damp-
ing.
Turn out one or two clicks.
Generally a stiff spring gives a stiff
riding feeling. Rebound damping
tends to become weaker, resulting in
lack of a sense of contact with the
road surface or in a vibrating handle-
bar.
FRONT FORK SETTING PARTS
•
Adjustment washer "1"
• Front fork spring "2"
The I.D. mark (slits) "a" is proved on
the end of the spring.
When using a spring with a spring
rate of 0.469 kg/mm, do not install
two or more adjustment washers
for each front fork.
REAR SUSPENSION SETTING
The rear suspension setting should
be made depending on the rider's
feeling of an actual run and the circuit
conditions.
The rear suspension setting includes
the following two factors:
1. Setting of spring preload
•
Change the set length of the
spring.
•
Change the spring.
2. Setting of damping force
•
Change the rebound damping.
• Change the compression damp-
ing.
