MAINTENANCE AND ADJUSTMENT
j
Rear Suspension (UNI-TRAK
®
)
This motorcycle’s rear suspension system is called
“UNI-TRAK
®
” and consists of a rear shock absorber
unit, a swingarm, two lever rods and a lever.
The operating characteristics of the UNI-TRAK
®
suspension are similar to those of the front fork.
However, a linkage system is used to achieve pro-
gressive springing characteristics.
Rear Shock Absorber Inspection
NOTICE
Sticking muds or dusts on the sliding surface
of the rear shock absorber could damage to
the oil seal, leading to an oil leak. Clean the
sliding surface after each ride.
•
Pump the seat down and up by 4 or 5 times, and
inspect the smooth stroke.
•
If it does not smoothly or noise is found, inspect
the oil leak and rear shock absorber mounting.
•
Visually inspect the rear shock absorber for oil
leakage.
•
If necessary, repair or replace by an authorized
Kawasaki dealer.
Rear Shock Absorber Adjustment
The spring preload of the shock absorber can be
adjusted or the spring can be replaced with an op-
tional one to suit various riding conditions. In addi-
tion, the damping force can be adjusted easily, mak-
ing it unnecessary to change the oil viscosity.
Rebound Damping Adjustment
To adjust the rear shock absorber rebound damp-
ing, turn the rebound damping adjuster at the bottom
of the rear shock absorber with a standard tip screw-
driver.
A. Rebound Damping Adjuster
If the damping feels too soft or too stiff, adjust it in
accordance with the following table.
