Periodic Maintenance Procedures
The torque of fork top plug is specified to 45 N·m (4.6
kgf·m, 33 ft·lb) however, when you use the top plug wrench
(special tool) [A], reduce the torque to 90% of the spec-
ified value [41 N·m (4.2 kgf·m, 30 ft·lb)] due to the dis-
tance [B] between the center of the square hole, where the
torque wrench is fitted, and that of the octagonal hole of the
wrench.
This torque value [41 N·m (4.2 kgf·m, 30 ft·lb)] is appli-
cable when you use a torque wrench whose length gives
leverage of approximately 310 mm between the grip point
to the center of the coupling square.
Torque - Front Fork Top Plug: 45 N·m (4.6 kgf·m, 33 ft·lb)
Front Fork Clamp Bolts (Upper): 20 N·m (2.0
kgf·m, 15 ft·lb)
Install the removed parts (see appropriate chapters).
Adjust the air pressure (see Air Pressure Adjustment
(KX450FD ∼) in the Suspension chapter).
Adjust the compression and rebound damping force ad-
justers (see Compression Damping Adjustment and Re-
bound Damping Adjustment in the Suspension chapter).
Improper fork leg adjustment can cause poor han-
dling and loss of stability, which could lead to an
accident. Always adjust the fork legs on the left and
right side to the same setting.
Tighten:
Torque - Air Valve Plug: 0.2 N·m (0.020 kgf·m, 1.8 in·lb)
Be sure to install the air valve plug to prevent dust
from entering.

Rear Shock Absorber Inspection

Bounce [A] the rear of the motorcycle up and down and
check for smooth suspension stroke.
Remove the rear frame (see Rear Frame Removal in the
Frame chapter).
Check for a broken or collapsed spring.
Check the shock for a bent shaft or oil leaks.
If the shock does not smoothly or damaged, replace or
repair defective parts.

Rear Shock Absorber Oil Change

The oil should be changed in the rear shock absorber at
least once per racing season. The frequency for best per-
formance must be based upon riding conditions and rider
ability.
Remove the rear shock absorber (see Rear Shock Ab-
sorber Removal in the Suspension chapter).
Remove the shock absorber spring (see Spring Replace-
ment in the Suspension chapter).
