TIP
Generally a stiff spring gives a stiff riding feel-
ing. Rebound damping tends to become weak-
er, resulting in lack of a sense of contact with
the road surface or in a vibrating handlebar.

REAR SUSPENSION SETTING

The rear shock absorber setting should be
made depending on the rider's feeling of an ac-
tual run and the circuit conditions.
The rear suspension setting includes the fol-
lowing 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 force.
• Change the compression damping force.

CHOOSING SET LENGTH

EASB296394
1. Place a stand or a block under the engine to
put the rear wheel above the floor, and mea-
sure the length "a" between the rear wheel
axle center and the rear fender holding bolt.
2. Remove the stand or block from the engine
and, with a rider astride the seat, measure
the sunken length "b" between the rear
wheel axle center and the rear fender hold-
ing bolt.
3. Loosen the locknut "1" and make adjustment
by turning the adjuster "2" to achieve the
standard figure from the subtraction of the
length "b" from the length "a".
